Caution:
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 220~240 V, 50 Hz in FM Tuner at volume minimum should be ~ 850mA (E).
Current consumption at AC 220~240 V, 50/60 Hz in FM Tuner at volume minimum should be ~ 850mA (GM/GS).
