I'm talking about the coil #12 the oscillator coil for now. #8 doesn't have a tertiary winding just two windings one with a tap.
Since there is no pin out for the coil base go ahead and tack #8 back in place and we can figure what pin go to what components. Then this will tell what sections are open on #8. Or just count the turns, measure the size of the wire with a micrometer and rewind.
One thing to look for is green dots on the windings. This is where the copper has rotted and that portion is no good. You can clean the wire just past that area and check the resistance to the other end for continuity. If good you can solder new wire (splice) for the repair.

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!
