Philco 20 - variable capacitor tuning
#7

+1
Sound like a bad rf coil. Fortunitly the primary (the smaller winding) of these coil is untuned so the number of turns isn't super critical. It most of the time is the outer winding on coil. Original is most likely 38ga magnet wire but any thing from 38 to 30 will work fine. You can approximate the # of turns by the size of the original winding, it's probably 20-50 turns. Unlike the osc coil in the the superhet sets direction doesn't matter.
Obtw Is it a standard, deluxe or consolette? Doesn't matter for the repair just curious, call me George.

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!
