President’s Report
“Radiogram” is our Club magazine,
published twice a year. This issue
No. 122 covers the period from August 2012 to February 2013. The
magazine complements our Club
Website, which is very ably managed by Reg Gauci with up to date
information on the Club activities.
On the 30th of September the official
opening of the Wireless Hill Station Centenary took place.
Our Clubs contribution to this was a display of wirelesses
from the 1920s to the 50s. Thanks to our members who
attended and helped in these activities.

Meetings are held on the fourth Tuesday of each
month (with the exception of December) at 8pm in
the Veteran Car Club rooms at 6 Hickey Street,
Ardross. Visitors are always welcome!
Although the main interests of members are wireless receivers and gramophones (or phonographs)
, many members are also interested in amplifiers,
telephones, musical boxes, tape recorders, television receivers and other associated equipment and
memorabilia.
On the 7th of October, our Club held a Valve Radio Information Day at Wireless Hill to which members of the public were invited to bring their old wireless sets to get information on origin, dating and restoration. This was well received by the public and some 60 people turned up with
radios. Special thanks to Rodney, Richard, Andrew and
Reg for attending and providing information to the public.
A number of radios were donated to the Club.
On the 14th of October at 10:30am Richard Rennie
launched his book – Encyclopaedia of Western Australian Wirelesses and Gramophones, at Wireless Hill. I
understand a large crowd of interested people attended
and book sales were brisk. Richard has more copies
available, so please see him if you are interested. Congratulations to Richard on his considerable work and success.
I was unable to attend the Christmas party on 27 Nov and
the January Auction on 22 January due to visiting family
over East. However I hear they went very well indeed and
I would like to thank those that made them a success.
Some photos from the Auction are included in this issue.
Radio-Gram is currently published twice per year,
in about February and August.
On 2 February 2013 Tony Smith organized a Club outing
to a private cinema owned by Roy Mudge in Medina.

The Secretary’s Report
The November social saw the conclusion of a very successful year
for the Club. About 20 members
attended and demolished the food
which was intended to cater for
about 40 – and a good time was
had by all. My thanks to Andrew
(drinks), Barry (salads), Stephen (buns), Reg
(cheesecakes) and the Melville meat supply who again
provided some excellent roast beef.
We can look forward to another programme of interesting
meetings this year, with again a good mix of guest and
member presentations, February will see Richard introduce the man who built the first radio in W.A.
In March we welcome Don Yates with his experiences at
6PM. John Rutland will talk on his experiences in the
electrical world in April and in May we have a “novelty
and interesting” transistor night with a short introduction
by Reg.
I look forward to an enjoyable year and seeing as many
members as possible at our meetings.
Some interesting meetings were held in the previous
months with a good balance between guest speakers and ............Rodney
member presentations. A feature of this period were the
Wireless Hill Centenary celebrations. The Club particiGuildford Festival
pated in the main “fun fair” day with a small display of
wirelesses and gramophones. A steady stream of visitors Dont forget the Guildford Festival on 24 March 2013. An
annual event held at Stirling Gardens, Guildford.
showed a keen interest in the items on display.
A couple of weeks later we hosted the Valve Radio Information Day and again we had a good response from the
public. A number of members and general public attended Richard’s book launch, which again was a success. The Club owes a debt to Richard for his part in the
organization of these events.
A further display was held at the Have a Go Day at Burswood, which again attracted good interest from the public. My thanks to Barry and Reg for their assistance on
that day.
As our exposure increases, much of which is due to the
excellent work of Reg on the website, we are seeing an
increasing number of donations, which eventually make
their way to our auctions, and then on to our bank balance. This has produced some storage problems and we
have introduced mini auctions at our normal meetings,
where we do not have a guest speaker. These are intended for donated items only, with members able to sell
at the main auctions in June and January. Initially it was
intended that the mini auctions be limited to 10 items, but
we have found that we can dispose of up to 30 without
undue stress, and this has helped keep the backlog of
items under some sort of control. Thanks are owed to
Tony Smith for his work in attracting, storing, and organizing auction goods.
Our Club will have an exhibit of vintage wireless and
gramophones. Will be under cover or inside.
Come along and promote our Club to the public, and help
round up some new members! Or come along to support
those members who are bringing along parts of their collections.
This is a fun day out, and there are many other Clubs
and activities on show.
30th Anniversary of our Club in February!
The January auction saw 61 Club items offered and 45
members items with most selling and on their way to
good homes.
Early in February a number of members attended a
screening of “This is Cinerama” at a private cinema. This
event was organized by Tony Smith, to whom thanks is
due, and from reports it was a successful afternoon

A Restoration Story by Fred Franklin
HEARWELL RADIO BUILT BY HEACO (ENGLAND)
Many years ago I bought a three valve radio from a PMG technician. He had a
"cathedral window" type of radio too. I preferred it to the Heaco, however, he insisted
on parting with the Heaco. In hind sight I am glad that I bought the Heaco as it may
be the only one in Australia. It worked well but deteriorated over the years
The radio had no speaker or head phones so I bought a
small Stirling horn speaker with an resistance of two
thousand ohms. It was in dirty condition but the electrics
were excellent. I cleaned the horn and noted that it still
had some of the original paint on it. Armed with this
important information I went to an automotive spare
parts shop that matched, mixed and packed their own
spray cans of paint.
I polished a brass ring around the small end of the horn
and masked it before hanging the horn on the clothes line
and painting it with a recommended primer, undercoat
and the Holden Commodore burned copper top coat.
Heaco Hearwell chassis from rear view.
The same treatment was given to the speaker's base. It
contains the electrics that work on the same principal as a head phone, but somewhat larger.
The headphones that I bought for the radio were in very good condition. Both the phones and speaker required new 1/4
inch plugs with PLASTIC bodies. The insulated body is important as the B+ 60 volts is present on the plug body because
of the use of 1/4 inch PMG telephone jacks. The speaker and headphones are connected directly between the B+ rail and
the anode of the relevant valve. The phones and the speaker coils are polarized and should be connected positive to positive and negative to the anode.
Heaco Hearwell chassis from front view.
There are three balloon shaped valves used in the radio.
These are all 01A described in the Phillips Miniwatt data
book as detector amplifier triodes and used as audio amplifier valves. Similar part numbers are UX-201A. The
"UX" describes the base and 2 describes the manufacturer. Two valves were good and one was open circuit
filament. A replacement was obtained from the valve
bank.
The pins are viewed from the bottom with the two fat pins lower
and the two thin pins above them. Starting at the lower left fat
pin that is pin1 filament (+5 volts @ 0.25 amp), pin2 anode (+90
volts @ 2.5mA), pin 3 grid and pin 4 filament negative. The
anode is also capable of using 135 volts @ 3.0 mA or 90 volts
@ 2.5 mA. I will use 60 volts as indicated on the battery connections label.
The two inter stage Western Electrics 3:1 audio transformers
were open circuit. I will pull them to pieces and rewind them.
Oh no! "Ten million" turns per coil of one thousandth of an inch
winding wire. I have neither the patience nor winder

for this job so they were replaced with Antique Electronics transformers, part number P-T156. They stand out like a sore thumb amongst the genuine, original, antique parts.

However, in our hot, humid climate I seem to be getting more than
my fair share of transformers with open circuit coils as a result of
humidity induced corrosion. I want the radio to go reliably for ever
with out constant tinkering every time that I turn it on.
The aerial transformer seems to be original and in good condition but
the regenerative coil was corroded and needed rewinding. The two
windings share the same former. The regeneration coil consist of
twenty-five turns of 5/44 B&SPF litz wire. The aerial coil has one
hundred turns of about 15/1000 inch ordinary enamelled wire tapped
at three, six and nine turns from the bottom of the former. I did not
unwind it to find out accurately as I prefer to leave sleeping dogs lay.
Litz winding wire consists of five strands of enamelled winding wire
bound together with a cotton covering. The equivalent is to wind the
coil with "five conductors in hand". The wire has special magnetic
properties that are excellent for radio frequency coils. When using litz
wire leave a fair amount left over at each end of the coil as cleaning
off the enamel insulation ready for soldering is a real task on wire that
is this thin.
Now to the cabinet that consists of the coffin with its lift up lid and a
small cupboard underneath with normal doors. The lid appears to
have been upholstered as a foot stool at one stage as there are upholstery pin marks all around the edge. Inside the battery cupboard the
Heaco Hearwell radio ready for listening
amount of filth reminds me that the family chook was living there.
Inside the coffin where the radio lives it was all smashed up and was probably a storage place for kindling wood for the
lounge room fire. What a cosy little box!
For the power supply I have used a number of small 12 volt
sealed lead acid batteries and a similar 6 volt battery. All
available from J-car.
After stripping out the electronics and cleaning and scrubbing everything, I applied eleven coats of shellac and linseed
oil. Now the cabinet looks really good, except for the pin
marks all around the edge of the lid.
Heaco Hearwell radio with battery compartment open
There is only one thing to do now re-assemble it and listen to
the news on it. On the A.M. scale we have ABC Radio National, Radio, 8 T.A.B., the aboriginal station and the Greek
community station.
Happy collecting and restoration.

CARING FOR YOUR DISC
RECORDS
Based on information supplied by the National Film and Sound
Archive Canberra.
How should discs be handled and stored?
Sound recordings need to be handled correctly to avoid
contamination or other damage. Even when your hands
appear clean, traces of sweat and oil are present which
can attract dust or promote mould growth when deposited on a recording. Unless being played or cleaned, recordings should be kept in their sleeves/boxes, which
also offer physical protection and resistance to damage.
Zip-lock plastic envelopes will protect against dust,
moisture and mechanical damage.
Discs should be stored in cool, dry conditions with a
minimum of dust and pollutants, and shelved upright in
sturdy shelves with dividing supports every 100 mm 150 mm. Changes in temperature or humidity, direct
sunlight, local heat sources, moisture, and dust
should be avoided.
How can you clean or restore discs?
Before playing, discs with light contamination (such as
airborne dust) should be cleaned by hand using a suitable brush. Keep a separate brush for 78's and LP's if
you have both.
ing solution is a 1% solution of cetrimonium bromide in
distilled water (available from well stocked pharmacies).
Rinse and dry with a soft cloth. If that is not available a
couple of drops of washing up detergent in luke-warm
water and a very soft brush will help get any grit out of
the grooves. They can be dried on a well washed tea
towel or just allowed to dry in a dish rack. Try not to get
the paper label in the middle of the disc wet.
What precautions should you take with
discs?
Any disc has a finite number of times it can be played
before the groove is damaged to some audible extent.
The turntable and pickup arm should be properly adjusted and maintained as well as having the correct stylus type for the discs. Any surface dust should be removed before playback.
A quality turntable and pickup cartridge will cost several
hundred dollars, although there are cheaper turntables
with a USB connection available quite cheaply. These
allow the audio signal to be directly recorded onto a
computer as mp3 files and burnt to CD or transferred to
an iPod or similar. Electronic filtering can sometimes be
effective in removing unwanted noise and the effects of
wear or damage. These cheap turntables are not of the
highest quality and repeated playing of a record will lead
to groove wear, but they can be useful for a one-off
transfer to a digital format.

collection can be found at

Old Valve Information Day—Sunday 7 October 2012
On 7 October 2012 the Vintage Wireless and
Gramophone Club conducted an “Old Valve Radio
Information Day” at Wireless Hill, inviting the Public to bring in any old valve radio sets for identification and dating.
The function was a great success with about 65 people attending with about 29 radio sets, which kept
your Club Reps very busy. Representing our Club
were Rodney House, Reg Gauci, Andrew Wakeman,
Rob Nunn and Richard Rennie. Thanks to these
members for their great work and for bringing along
some radios and gramophones for display.
We also had the following items donated to the
Club:
Bag of valves
60s Kreisler radio
STC Bakelite radio
Home made 1 valve receiver
Astor car radio with cable controls
Early Sharp 10 transistor radio
Some of the sets brought along for display

Restoration of a 1928-30 Console Radio
By Phil Oxwell
Following on late last year from the restoration of my 16 valve
Midwest Radio, I tackled another project being a small console
radio.
I had called to see the seller in Carlisle as he had described it
on Gumtree as a” large mantle” radio and I was looking to do
another restoration on wood radio.
When I arrived it was indeed the size of a large mantle radio,as
someone in the distant past had done major surgery on the legs
by removing them .He advised me he had purchased it 20
years ago from a lady in Dalkeith and he was to restore it but
never got
around to it and it had sat in his back-shed for all the time
Being new to the radio collection scene I was not even aware
the legs had been removed until it was pointed out to me by
Andrew Wakeman when I sent him a photo to help identify the
set.
Good news was that Andrew did indeed have a set of legs from
the same model case radio that he was willing to part with.
The make of the radio is a New Systems Radio
(Hollingsworth) and it has a plaque at rear of case that the
case was made by a company in Sydney called Ricketts and
Thorpe who was a very high end furniture maker company
from 1912 until mid 50s or so the description goes based on
internet information.
New Systems Radio (Hollingsworth) before restoration
The chassis was removed for restoration and then I started
on the case by stripping back the old varnish and perhaps
the original stain which was used to “darken” the original
wood.
This took a lot of manual labour (they all do) as I don’t like
to use a great deal of heavy grade sandpaper starting with
120 and then finishing on 240 and then, 000 steel wool. I
had by then re-attached the 4 replacement legs and they now
look great.
The wood cabinet itself did not require any wood repair so
this was a good thing .After applying several coats of Feast
Watson sanding sealer and then taking back again with fine
wet and dry paper I then lightly stained the wood with a
shade of light teak and maple, again using Feast Watson
proofing product as I find that this brand colour matching is
pretty well spot on.

The final process was 3 coats of Polyethylene The end result shows grain of
wood and the veneer that would never have been seen under the original
staining varnish and looks a beautiful radio and also plays like a beautiful
radio and now sits in our formal lounge area of our home.

Amplifiers and interesting equipment
from club member, Alex Koppen, in
the U.K.
One is of a V24 valve with the original box which is
very rare. The item that looks like a morse code key (but is
not) apparently I've been told is the same item as in some pictures of the Titantic's radio room, but of course I have not
seen this and I don't think its true but its quite an interesting
piece. Obviously not the one from the Titantic!
Theres also here a Greives Cotton and Co of Bombay Electrical Engineers item - Its called a full wave magnetic rectifier.
230 volts, 50 cycles. Quite an interesting lump of iron! Made
in Bombay.

The amplifiers have 2x Eimac 100TH valves in each. I had
them made in Western Australia.
Originally each amp had round toroidal transformers. Both
didn't last long at all and I never liked them, they were made in
Sydney.

very unusual beautifully reconstructed 1907-8
Klingsor gramophone.
Amplifier valves at night!
I ordered 2 from Magestic Transformers, of Dorset. Not
round ones, and they seem to have been working fine since.
Each amp has a name, once's called Love, the pre-amp is
called 'N' and the other amp is called Peace. The sound is
wonderful. No base or treble, just 2 volume controllers.

avenues to come up with a solution but suspected, it
was due to one of our rectifiers.
My Favourite Wireless
by James Wemm
Before I start on about my favourite wireless from my
collection, I would like to share with you an experience I
had many years ago when I used to work for a living,
that is, prior to going into teaching. This memory was
prompted after attending the film afternoon arranged by
Tony Smith which turned out to be a great experience.
Now I originally worked for a company you all would be
familiar with and that is Standard Telephones & Cables
(STC). When I started with them back in 1967, they no
longer manufactured consumer products such as radios,
fridges, vacuum cleaners Television sets etc. They were
taken over by ITT (actually IT&T International Telephone
and Telegraph) and the company then concentrated on
three main products, Telephone, Mobile Radio and Industrial Electronics.
The main factory was located on Botany Road in Alexandria, NSW where they manufactured large and small
telephone exchanges or PABXs and their range of mobile radio units. I was located in the Melbourne office
where I worked in the Industrial Electronics section. Now
this section encompassed everything from PA systems,
sound reinforcement, pocket paging systems, rectifiers
and power supplies etc. In other words, everything that
was not telephone or mobile radio related.
One of the jobs we were involved with at the time was to
provide the large rectifiers for the new Xenon projectors
at Hoyts Cinema Centre in Bourke Street Melbourne,
which was under construction at the time in 1969. The
rectifiers were manufactured by STC at their Liverpool
factory in NSW. From memory the rectifier provided 25
volts at around 160 amps and there were two installed in
each of the three cinemas in the complex. One rectifier
for each xenon projector in each of the Bio boxes.
Now the problem related to an audible ‘hum’ in the amplifying system when using one of the projectors which
was not present in any of the other units.
So arriving at the Bio box in Cinema 2, I was met by the
head projectionist and some heavies from Hoyts who
indeed were pointing the finger at one of our rectifiers!
Where to start? Well I quickly deduced that the ‘hum’ in
the audio system was a 50 hertz signal so straight away
it ruled out interference from rectified DC. I also was of
the opinion that our rectifier was in the clear unless it
was due to electro-magnetic radiation from the large
power transformer contained within. I also ruled this out
as none of the others suffered the same problem and it
was contained in a pretty sturdy metal cabinet which
should act as a shield.
Back to the projector and peering into the section where
the audio amps were with all their connections I was at
my wits end and was probably hoping for some divine
intervention. I was about to recite Ohm’s law to the projector to let it know it was in fact dealing with a qualified
Electronics techo when I noticed that there was something different in the base of this projector compared to
the others. The difference revolved around how the 240
volt power was brought into the base of the projector.
Originally, both the Xenon projectors were apparently
fed from the one circuit breaker where it was supposed
to have a breaker for each unit. Makes sense really.
So the contracting electricians left the parallel connections in situ and just disconnected the active and ran a
separate active in a conduit from the fuse box without
the neutral. Seemed unlikely that this could be the problem however, the radiation from the active conductor
without the cancelling effect of the neutral and vice versa
can be quite significant.
Contracting electricians installed the units along with all
required cabling for both the projectors and the rectifiers.
We were merely required to commission and test the
rectifiers with the Hoyts personnel being present for the
handover. There were also people there from Gaumont
Kalee theatre supply company, the makers of the xenon
projectors. All went well and the handover was completed and signed off. This was not done by me but
some of the more senior personnel at STC down from
Sydney.
About three months later when I had taken up the position of senior service technician, I received a call from
the Cinema centre saying they had a problem with one
of the projectors in Cinema 2 and although they couldn’t
confirm if the problem was ours, they were exploring all

Clutching at straws I asked if the electricians were still
working in the complex and if so, could they be contacted
to come over with some heavy duty twin and earth. All
the heavies in the Bio box looked at me like I was from
outer space and I must admit I was starting to sweat as I
was not really sure if it was going to work.
The electrician duly arrived and was clearly not pleased
with what I wanted him to do. I wanted him to totally disconnect the projector from the 240 volts in the base of the
unit including the Neutral and earth and run a temporary
feed from the fuse box over to the projector. I don’t think
the people from Hoyts including the Head projectionist
had much faith and were actually quite amused at what I
was doing, however didn’t say much as they were unable
to come up with a solution to the interference.
Time for the big test, breaker on, projector on, amps on
and lo and behold, absolutely no hum!! Not convinced,
they loaded a film onto the projector, turns out it was the
Thomas Crown affair with Steve McQueen and then
started the movie. Still no hum through the headphones
on the projector! Then all went down into the Auditorium
– same result no hum.
Upon their return I was congratulated on my efforts and
was told Hoyts would be in touch with me personally. After a couple of weeks I received a year’s supply of free
movie tickets which was a nice touch however all in a
day’s work for the electronics tech eh!
PS I don’t think the electricians were too popular with the
Hoyts people.
So getting back to my favourite radio!
Looking at my collection
of wirelesses and radios
(they seemed to change
the name sometime in
the late 1930s) my favourite
unit
would
probably be the Airzone
‘AirPlayer’
console
model. Now I am only
assuming it is an Airzone as the name does
not appear on it anywhere apart from the
Airplayer nameplate on
the dial escutcheon.
The main reason I am
assuming it is an Airzone is that the circuit is
identical to the Airzone
505/515 from around
1932 and the details being printed in Silicon Chip in their
antique radio section back in July 2002.
I purchased this radio from the ‘Restorer’s Barn’ in Castlemaine Victoria. This place sells everything you could
possibly want when restoring an old house or furniture
etc. Original brass and ceramic light switches, old taps
plus thousands of other bits and pieces. They also operate as an antique shop selling a lot of items on consignment such as radios, furniture and all the other junk that
seems to be in every antique shop. Wandering through I
spotted this console radio looking forlorn and clearly in
need of serious restoration.
Incidentally STC also provided all of the lamp dimmers
for all three theatres and the foyer areas. So what you
might say, lamp dimmers have been used in theatres
probably dating back to silent movies! However, the interesting thing about this was the fact that we were dimming fluorescent lights which to my knowledge, had not Further inspection revealed that the cabinet was in reabeen done in a theatre before.

The main reason that I wanted the wooden console unit
was that my partner had enrolled in a French Polishing
course and as part of the training she was encouraged to
bring along something to work on.
So after getting them home I quickly stripped down the
unit ready for some pretty serious cabinet work. So while
my partner took the unit off to night school I started to
restore the actual radio. .
commenced to rotate the tuning dial and to my pleasant
surprise, in came 6PR loud and clear!
Now although this unit hails from around 1932, it is a Superheterodyne with an IF of 455KHz where most units
around this time had an IF of 175KHz or were still TRF
types. The circuit does not have a volume control and
instead, uses a gain control in the aerial circuit. This
leads to loud clicks and pops emanating from the unit
when turning on lights etc. Also the audio is a bit distorted
as it uses an anode bend detector which compared to
today’s detector circuits leaves a bit to be desired
The Airzone 505 circuit diagram.
Sent the Speaker off to a chap in NSW for a re-cone and
test having first deduced that both the field, and voice
coils were ok along with the output transformer. The
speaker assembly came back looking like brand new.
I did a general clean up and rust removal on the chassis
and then replaced all capacitors and any resistors that
measured suspect. I also replaced the 80 rectifier which
was cracked and also the 3 core flex and power plug with
some new brown cotton covered cable and a near new
brown Bakelite 3 pin plug.
Now with the rectifier removed I connected the unit to a
Variac and slowly increased the supply voltage while
measuring the secondary HT voltage. All good with the
filaments and dial lights alive. Reducing the supply voltage back to zero and plugging in the 80 rectifier again,
repeated the process, this time measuring the main HT
voltage and was pleased to see it climb to around 400
volts. Even more pleased to hear a slight hum in the
speaker. Then connecting a 2 metre wire for the aerial
21
There is also no AGC so when tuning to different frequencies, the gain control needs to be worked on to provide a satisfactory output from all radio stations.
Now this radio is allowed to reside inside the house
whereas the others are relegated out of sight. Might have
something to do with the French polishing!!
PS Please let me know if you think this unit is not an Airzone but another brand of a company operating in the
1930’s, bearing in mind that the unit was purchased in
Victoria.

This system was, I understood, used before such converters as pentagrids (as 6A7) and triode-heptodes (as
6J8) came along.
AIRZONE 300
By Tony Smith
I had never had to deal with one of these but tracing
the circuit, and having a vague idea of how they
worked enabled the front end to be worked out.
One day I noticed an old
radio in the corner of the
garage of one of our
members.
It was an Airzone 300
in a wooden cabinet,
the cabinet looking as
though it had just been
re-furbished. With a
Once the set was out of the cabinet the speaker was removed. It was an electromagnetic speaker whose magnet
coil winding was fortunately intact - but - Boy! There was
this repair made to the speaker cone to cover some obvious insect holes with newspaper. I had never seen a repair
like this before, and it turned out that the member owner
had done the repair.
Airzone 300
rush of blood to the head I said to the member - I
would love to have a go at getting that old set going.
Before I could say "electrolytic" the set was in my car's
boot! Talk about a big mouth!
The line up of valves in these sets are 57 - 58 - 59 - 80
With no circuit
one could be
forgiven for thinking that it might
be a TRF as
there appeared
to be no frequency converter.
Top view of chassis
Rear view of chassis
He explained that to prevent the voice-coil from touching
the central magnet when the paper and glue dried some
shims had been placed around the core - to be removed
later. Would you believe that this worked and the speaker
was useable! A close look at the paper used indicated that
it was part of a published cartoon strip by the artist "Sots".
Maybe someone could date this bit of paper!
Taking the set out of the cabinet and endeavouring to
draw out the circuit soon indicted that the set was in fact
an early superhet, with a standard pentode valve as a
frequency converter, an IF stage, and an output stage
acting as a detector-amplifier. The converter was what
we used to know as an "autodyne" utilizing a standard
pentode as a combined oscillator and mixer.
A new trend in speaker repairs!
Heres a complicated chasis!
22
Continuing to trace out the circuit was not all that easy as
connections to the coils and IFs were not identified - although with the use of an ohm-meter and the valve connections a rough circuit was finally done.
Radiogram Issue 122 February 2013
23
The set was designed before AGC became the norm, and
tracing out the circuit showed that the "volume control"was
in fact a "gain"control, consisting of a combination wirewound rheostat that partially loaded up the aerial input and
at the same time increased the bias on the IF stage. The
bias voltage came from a resistor divider network from the
screen supply putting a positive and adjustable bias on the
IF cathode.
All the wire-wound resistors had an opened circuit, probably due to corrosion over the years. As it was calculated
that the currents involved in the appropriate circuts were
relatively low it was decided to use high rating carbon

auction at the February meeting

“gain” control and the aerial/oscillator coils
resistors as replacements. The accompanying under
chassis photo shows the original wire-wound resistors,
and also the aerial and oscillator coils and cans mounted
under the chassis. Also seen in this photo is the gain control rheostat.
In the meantime a request was sent to the Historical
Radio Society and their circuit diagram service, and
sure enough back came the exact circuit of the set,
originally drawn in January 1933.
Plenty of spare parts up for auction at the
February meeting
Then it was time to try. Taking the usual necessary precautions the set was gradually brought up to being directly on the mains. And naturally there came the stations! The performance was low and upon checking the
HT it was obvious the 80 was not too good. An adaptor
was mad up to try a 5Y3 and this made a big difference
to the voltage and the set's showing.
The set was returned to the grateful owner with the poor
80 rectifier still installed, and whilst the performance left a
little to be desired it certainly was reasonable and all the
locals came in with a good aerial.

Cinerama!
On 2 February 2013 Tony Smith organized a Club outing to a private
cinema owned by Roy Mudge in Medina.
Thanks are due to Tony Smith and his friend Roy Mudge for this very
interesting film afternoon titled “This is Cinerama” . I have heard very
favourable feedback from members that attended.
Cinerama is the trademarked name for a widescreen process which
works by simultaneously projecting images from three synchronized 35
mm projectors onto a huge, deeply-curved screen, subtending 146° of
arc. It is also the trademarked name for the corporation which was
formed to market it. I
t was the first of a number of novel processes introduced during the
1950s, when the movie industry was reacting to competition from television. Cinerama was presented to the public as a theatrical event, with
reserved seating and printed programs, and audience members often
dressed in best attire for the evening.

The Phonograph & Typewriter Co. began in June 1907. It grew out of The Edison Phono. Depot which had been
started in 1904 in a small shop in Central Arcade by Herbert R. Firth. Central Arcade originally ran between
Murray Street and Wellington Streets, opposite the Perth Railway Station, through what is now Forrest Place. About
January 1907 the sole agency in Western Australia for the Moya Typewriter was granted to the Edison Phono. Depot. It was thus decided it was more appropriate to change the name of the company to The Phonograph & Typewriter Co. The first advertisement for The Phonograph & Typewriter Co. appeared in June 1907.
