CONNECTINGNECESSARY 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.
IT CONNECTS WITH A MAINS SUPPLY VOLTAGE IN AUTORANGING 90 – 265 VAC @50/60 HZ.
AMPLIFIER IS READY FOR WORK AFTER INSERTING TUBES 6C33C IN THEIR SOCKETS.
TO DRIVE THE FULL POWER NEED INPUT VOLTAGE 2.0 V RMS TO CONNECT ANALOGUE TYPES RCA PHONO
FRONT THE INPUT AUDIO SIGNAL IS 21 POSITIONS STEPPED ATTENUATOR FOR VOLUME CONTROL.
SPEAKERS TO CONNECT TO THE BINDING POST BEFORE RUNNING POWER. DISCONNECT THE SPEAKERS WHEN THE POWER IS TURNED OFF.
THE MAIN RED BUTTON SWITCHES IT ON.
AMPLIFIER READY IS AFTER 120S, TO FULLY WARM THE TUBES SEVERAL MINUTES ARE REQUIRED.

RESISTANCE TO TEMPERATURE AIR CIRCULATION UNDER ITS BOTTOM
CAUTIONYOU 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 THE AMPLIFIER IN COOL - AIRY SPOTS,
FAR FROM ACCIDENTAL REACH TO AVOID RANDOM TOUCH AND BURN.
THE SHELVES, WITH ITS BOTTOM LIFTED ON STANDS TO ENABLE AIR CIRCULATION UNDER ITS BOTTOM.
