Philco 71 restoration
#21

Me thinks your right about the osc coil. Go head and rewind the small portion at the bottom of the coil. That's the feedback winding. It's 25t of small gauge magnet wire 30 to 38g is fine. Looking from the bottom of the coil it is wound clockwise. If you wind it backwards it won't work.

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!
