2 Before Repair and Adjustment

TOP PREVIOUS NEXT

Disconnect AC power, discharge Power Supply Capacitors C527-C530, C561 through a 10 Ω, 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 120V, 60Hz in NO SIGNAL mode should be ~850 mA .
