OK...not too clever, but whilst trying to measure the input voltage on one of the regs in my amp (G&W TWJ1) I slipped and shorted accross in/out. I turned off the amp quick, but the op amp after the power supply still went up in smoke
.....yes, thankyou, I know I'm a numpty
Anyway, I've replaced both regs and the op amp and the amp is working and sounding good...BUT....when there is no source connected to the RCA's I'm getting quite a lot of noise coming through the headphones (buzz) which increases in volume when I turn the pot...as soon as I connect a source to the rca's the noise dissappears entirely.
Is this some kind of ground issue? As I say, with a source connected you'd never know there was a problem
Any ideas gratefully received!!
