Philco 38-690 restoration
#17

The cabinet is completely finished. I'll take a photo when I have good light.

The good news is that a cd player to the top of the volume control gives audio output. The bad is that there is no radio reception. When I touch the grid caps on the 1st IF, 2nd IF, and RF-AVC tubes it produces noise in the speaker(s). The same with touching the grid caps on the RF, mixer, and oscillator tubes, although less so.

The next step may be using a signal generator to try to inject a signal at various locations to isolate the problem area(s).
