Philco 81 Questions
#40

If the 2ndary (large winding) is showing continuity I'd leave it alone. It's much more critical than the primary (small winding) as it determines the operating frequency of the oscillator. All the primary does is create feedback so the oscillator will run. It doesn't have much to do with frequency.

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!
