Hi Craig and welcome,
1st off the loop has two connections one to the rf side of the tuning cap and the other to the avc line. If the avc side isn't connected that could give the problem you describe.
I'd check the spkr to be sure the voice coil isn't rubbing on the pole.
Check voltage @ pin 5 of the 50L6 should see abt - 7vdc.
Would think that the avc line would be abt - 4 or -5v when tuned to a strong station.
Grew up near Silver Spring (Sandy Spring) but have been up in Pa (near Philly) for the last
30 yrs.

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!
