Thanks, and yeah I thought so too. I plugged it in to try it out and it seemed to be just a 60 hz. hum coming out of the speaker and no reception on the tuner so I'm guessing that the filter capacitor needs to be replaced at least, which is a 2000 MFD 30V electrolytic capacitor. As for the grille cloth it looks like it should be fairly easy to repair it. When I opened it up it looked like i was the first one to ever open the unit up as it still had its sound dampening pillow inside the case yet and it was pretty clean inside hardly a spec of dust inside the unit.

I have used a product called "goof off" successfully to remove latex paint splatters without damaging the underlying wood finish on older radios... I suspect that it would work ok on the KLH.

Alright, I'll see about picking up a bottle of that. The only problem is that there's some paint spatters on one of the knobs as well and I tried scratching it off with my fingernail and it wouldn't come off and I know goof-off isn't going to be good to use on something like plastic because it has stuff in it that hard on plastic, so I wonder what I would use on the knobs to clean them up.

OK, I'll see if I can find some.

Well I replaced the original 2000 MFD 30V Power Supply Cap in the radio with a 2200MFD 50V capacitor and its still has a 60Hz Hum coming out of the speaker and still no audio out of the speaker from the tuner. So what should I check next in the circuit that could be causing my issue? I also tried posting this in AudioKarma but for some reason when I went to post it it wouldn't post it would act like it was going to post the thread but then it would wouldn't actually post anything.
