Recapped model 80 and have problems
#3

As Steve said You should measure a very low resistance across those two points on the order of 10 ohms. If it is much higher you with need to rewind that part of that coil. It's pretty easy. http://www.philcorepairbench.com/tips/svctip36.htm
On the model 80 I'd go with 25 turns turn of #32 to 36 wire. As you might know these 4 toober are not the hottest sets. It may require a good outdoor antenna to get good reception. I just finished up a model 600 which is about the same as your 80 it had a few resistors that where out of tolerance and an open osc coil. On these superhet/regens It's important that all of the caps, tubes, and resistors are in good shape to get the maximum performance and smooth regeneration.

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 it!
