i have a donkey kong monitor i am almost giving up on. had no image, no neck glow. recapped chassis. now has neck glow and dim , shrunken image. B+ stuck at 88v. no adjustment at all. i replaced ic601 regulator, q901 transistor, Vr601 B+pot, flyback. all solder joints gone over, no cracked traces. i do get 130 volts from the power supply area of the chassis and 130v at the collector of q901( disconnected). hooked up, i get 88 volts, steady, no adjustment.
