Sorry to bother you all again. I was cleaning about 40 years of smoke
off the chassis and afterwards noticed that one of the "leaves" on the
oscillator section of the main tuning capacitor was bent. I assumed I
must have done it while cleaning and straightened it back out before I
gave it much thought (how most mistakes happen). Then it dawned on me
that the last "leaf" of each section (there are 3 sections) is broken
into easy bendable "tabs" and is not a solid semicircle. So some
adjustment was allowed for. Now I am thinking I may have altered what
should have been.


Rotsofluck. Gads... That was probably a factory only adjustment.
Your best bet is to carefully check several positions across the dial
for dial tracking errors. What you will have to do is carefully adjust
each plate (starting fully meshed) for minimal dial error. As you increase
frequency, the moveable plate about to unmesh is the one you want
to adjust for frequency (osc) and strongest AGC (RF/Mixer). Here's
the rub... The mechanical alignment interacts with the electrical
alignment..
One shouldn't sub for the other. So, first thing is to see if the radio
is working good enough at this point. You might be best leaving it
alone??
