NECESSARY IS AC POWER PLUGS MUST BE
CONNECTED TO THE EARTH (GROUND).

EACH AMPLIFIER UNIT IS RECOMMENDED TO
CONNECT TO AC POWER SOCKETS OF INDEPENDENT
THREE-PHASE ELECTRIC POWER.
AMPLIFIER IS READY FOR WORK AFTER INSERTING
TUBES 6C33C IN THEIR SOCKETS.
TO DRIVE THE FULL POWER NEED INPUT VOLTAGE

CAUTION
YOU MUST NOT TAKE OUT TUBES DURING
WORK – IT MAY RESULT IN BURNING ONESELF.
THE AMPLIFIER WARMS UP SUBSTANTIALLY
DURING WORK BECAUSE OF CLASS-A
OPERATION MODE.
IT IS RECOMMENDED TO LOCATE
AMPLIFIER IN COOL - AIRY SPOTS,
neutral range of living room temperature
up 18°C / 64°F to 22°C / 71.6°F
THE
FAR FROM ACCIDENTAL REACH TO AVOID
