2 Before Repair and Adjustment
TOP PREVIOUS NEXT
Disconnect AC power, discharge Power Supply Capacitors C1702, C703~C706, C742, C901, C904
through a 10 Ω, 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 450~1000 mA.
