model 38-10 no reception after recap
#9

Tada! we got it. It seems that either #15 is open or #5 between pins 4 and 3 are open. Which ever you need the 130v or so on the plate pin of the oscillator section of the pentagrid mixer and it's getting lost down by #15.
With the set off measure the resistance across pins 3 and 4 of #5 (oscillator coil). Should see a low resistance like an ohm or so. If not remove the coil and give it a close inspection for rot (green spots) or a break in the wire.

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!
