4 Before Repair and Adjustment (Using Active
Subwoofer)
Disconnect AC power, discharge Power Supply Capacitors C546~C549 through a 10
Ω
, 10 W resistor to
ground.
DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy
solid state devices.
After repairs are completed, restore power gradually using a variac, to avoid overcurrent.
Current consumption at AC 230-240 V, 50 Hz in NO SIGNAL mode should be ~ 1000 mA.
