There's 2 other things that are important. The FC connects between the two electrolytic caps in the power supply circuit. The VC connects the secondary of the output transformer.
If you look at the VC and the opt circuit on the schematic you'll see something that looks odd. The VC is facing one way and just below there's another coil facing the other way. This coil is placed on top of the FC and is completely separate electrically. It's called a humbucking coil and it bucks hum do to it 's out of phase relationship w/the VC and it magnetic field from the FC
Geez your going to be a rocket scientist after you get this project done.[Image: https://philcoradio.com/phorum/images/icons/smile.gif]

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!
