If you follow the hv around thru the 6C4 osc tube the plate and cathode should be at about the same potential. Unless the variable cap is shorted (rubbing plates). I think it's about 80vdc. RF wise the plate is at ground thru that .01 cap.
I'm assuming you've replaced the caps, out of tolerance resistors, and the power supply is making 140vdc or so at the cathode of the rectifier. Q Tips and denatured alcohol does wonders for the switch contacts.

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.

Now I think I've got!
