Success! I want to thank the folks who had suggestions for fixing the Dial mask. I ended up doing a combination of them and got it back together nearly flat. It was warped before so it is actually turning in the chassis much better.
After much troubleshooting I found an open 7.5K wire-wound resistor mounted on the sidewall that was open. Fastened one in parallel to it and the radio came to life, good AM reception, sporadic reception across the other bands.
The audio is real weak unless I hover my hand hear the tuning capacitor. If I hover my hand over it, the volume goes way up, I'm guessing this is a reception issue or a shielding issue. If I place my index finger on the wire connected to the top of the 6S7G that is connected to the top of the tuning capacitor, the signal clears right up, crystal clear.
Is there more than one issue here? Low power, shielding or am I acting like a great big antenna when my hand gets close to the tuner?
I've got all the lights off in the garage thinking it might be the fluorescents, the only other item is the main circuit breaker panel is only about 4 feet away from my workbench though I don't hear any 60Hz hum overriding anything.
Thoughts?
Cheers, Link
