Hi Chris,
Yes older big chassis sets w/ the worm gear in the front and back are a pain to restring. Common issues to pre '36 or so Philcos are open primaries on the rf coils, oscillator coil feedback winding open, fairly rare to find a bad if transformer, open audio driver and sometimes output transformers, spkr field coil open.
Sounds like you've dodged the bullet on most of these but would check the ant coil primary, this might be the cause of the good reception where touching the 24 cap.

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!
