I used a signal generator to inject a signal at the grid cap of the 6A7. It came through loud and clear.

I am trying to check the oscillator coil. If I am looking at the right part, it has five lugs coming off an open cylinder?... I've got continuity on 4 of them. I can also post ohm readings if need be.

BTW - I found the cause of the overheating cap. I put the old 80 tube back in the chassis. The cap exploded. Puhpow. Plate to filament short.
