Hi Rich,
Methinks Mike is looking at the wrong schematic (the one for model 50 trf set)
Unfortunately the info from Rider's doesn't show the placement of the trimmer adjustments. One thing to take note of is when you adjust any of the trimmers is there a peak in the signal when adjusting the rf and IF? Does oscillator frequency change when adjusting oscillator trimmers? If not this is a clue as to which coil may be bad.
Prime canadets are the cathode winding on the 24 mixer tube and the antenna coil. An ohm meter is your friend to find the bad one. All good coil will show a low resistance like 10 ohms or less

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!

Terry

If you have rust between the vanes, I wonder how you get the NJ in between, and how you then wipe it off.morzh — 12:02 PM

If the noise is still there, the OPT might just be OK. Or so we hope.morzh — 12:01 PM

You would probably be replacing the OPT.RodB — 10:54 AM
