Zenith H725
#71

Here's what the inside of AM IFT2 looked like, and the other pic shows the discs I made to take place of the mica and keep the contacts from short-circuiting.

   

   

I completed the recap, which called for 2x 120 pF and 180 pF and the radio is working again, but STILL crackles. I'll need to go through the remaining FM IF cans to solve this one. It will be a bit of a slog, and I'll probably need to order some more caps, as I don't have the smaller values found in the 10.7 MHz transformers. At least my OCD was right after all  Icon_lol

I don't hold with furniture that talks.
