I'm in the homestretch (I hope). I reinstalled the tone control, cleaned the band switch and found a new volume/power switch.
The one that came with the set was 1M but should be 350K.
This 450K is the closest I could find and it has a really smooth action. If it works out well, I'll have to cut down the shaft.
All 3 grid cap leads need to be replaced including this one on an IF can.
Here's the icky, gooey coil I found inside
It seems the old wax has bubbled over the years. Or maybe the coil form has outgassed ?
I wired in a new lead and hit it briefly with a heat gun on low to reflow the wax.
Almost done
