Gee, I wish I knew more about radio!
You won't believe this (or maybe you will). It wasn't the tuning capacitor at all! There was oscillation coming from the wire going from the oscillator coil to the grid cap of a 39/44 tube. I noticed if I put my hand in a certain position, the oscillation went away. To cut to the chase, I turned a screw on an ugly trimmer assembly on top of the coil, and the oscillation went away-- Live and learn? Thanks for your kind attention!
