OK, I found out about the antenna coil. I just took it out and checked it and there was a small primary that was damaged, so I rewound it and now the SW band works fine. My Am band still has some funky IF issues, as in when I tune to stations on the lower portion of the band, the audio is overpowered by whistles. Seems like they all track fine, and the higher on the band I go, they sound normal. I am using a signal tracer to hear them, though.

My real issue today is somehow, I have not been able to figure out why the audio signal is not appearing at the grid (or the plate) of the 75 tube. I've replaced the tube, caps, checked the resistors, and checked the volume control and still am working on getting sound out of the 2nd detector. I've injected a signal into my final amp (the 42 tube) and it works fine. ??? Help would be appreciated. Thanks. Ron.
