1. Before Repair and Adjustment

Disconnect AC power, discharge Power Supply Capacitors C607, C635 and C637 through a 10
5W 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 240V, 50 Hz in NO SIGNAL mode
should be ~200mA.
