GE Wildcat Issue

I have a GE Wildcat, it has a problem with the left channel. If I move the balance all the way to the left the chassis becomes "amplified" ie. if I tap on the chassis it is amplified through the speakers. If I move the balance all the way to the right, the chassis is not amplified and I can tap on it without hearing it amplified through the speakers. Do you guys know what might cause this? Thanks!

The condition is called microphonics. Check for loose connections / broken solder joints, could also be a bad capacitor. Use a nonconductive probe (wood, plastic or ceramic) and lightly tap on each component. Usually the closer you get to the offender, the louder the noise.

One of the smaller capacitors seems to be a little louder when I tap near it. Would that most likely be the culprit?

Very possible. You can try heating up the solder joints on & near that cap. If that doesn't take care of it, then I would go ahead & replace it.

That did the trick, re heated all the capacitor joints and it magically went away! Thanks so much!
