Well, with the replacement tuning assembly, I have finally put the unit back together and aligned the dial.  The first station that came in was a local station and the dial was only 5 KHz off -- an easy adjustment.  Btw, the ones that did come in were very clear.

I have started the tuning process with the broadcast band.  I don't have an antenna and even the really local stations don't come in unless I am touching terminal #1 with my finger.  Even with that, it only picks up stations from 1250 KHz and up.  Looking at the audio out with an oscilloscope, the signal simply flat-lines when it gets down to 1250 and stays that way to the bottom of the band -- like it is being muted.  Makes me think of that little custom-made plastic strip that I didn't know where to put back in the tuner.

Trimmers 36A (gang 1 to RF Amp) and 36B (gang 2 to Det-Osc) look like someone thought they were mounting screws and are tightened all the way down.  When I adjusted the other trimmers, they seemed to be working correctly, and it was easy to find the peak.  I'll loosen 36A & B tomorrow and see how it effects things.

Tomorrow I'll start tracing the signal from my signal generator.  I saw a couple of articles/posts/YT vids on tuning.  I expected to hear the output and be able to tune it by sound but that didn't happen.  Also, none of the ones I reviewed said what the two input voltages (when injecting into the Det-Osc control grid and when injecting through the antenna terminal) from the signal generator should be -- my sig-gen can be set from .1V to 3V P-t-P.  So, if someone knows what they should be I'd appreciate hearing.

I'll post back tomorrow with my specific findings/results.
