There was no double peak on the IF transformers but I did find out that three of the four trimmers were just about bottomed out and the fourth was about half of a turn from the bottom.

Trimmers were cleaned when I had the tuner assembly apart for repairs to the push buttons.

I also measured the oscillator coil, out of circuit and found the the coil resistances were within 20% of what the schematic shows. DC voltages were checked and were well within tolerance.


I think I’m going to set this aside until the weekend. Then I will open the tuning caps all the way, hook up a signal generator and oscilloscope to the oscillator coil and see exactly where it peaks out. I’ll post the results of my experiment.
