2 Before Repair and Adjustment
TOP PREVIOUS NEXT
Disconnect AC power, discharge Power Supply Capacitors C506, C507 and C508 through a 10Ω, 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, 60 Hz in NO SIGNAL mode should be ~420mA.
