2. Before Repair and Adjustment
Disconnect AC power, discharge Power Supply Capacitors C703 - C706, C901, C904 and C1702 through a 10 , 5 W resistor to ground. DO NOT SHORT-CIRCUIT DIRECTLY (with a screw driver blade, for instance), as this may destroy solid state devices. After repairs are completed, restore power gradually using a variac, to avoid over current. Current consumption at AC 120 V, 60 Hz in NO SIGNAL mode should be 400~1200 mA.
3. Protection Circuitry
The protection circuitry may have operated if either of the following conditions are noticed:
