Would check #14 100k resistor. If drifted lower in value this will raise the voltage. Poor ground at #14. Weak 24A. Clean heater contacts on socket & tube (24A det). Just for grins you can try grounding the control grid (grid cap) and check the plate voltage. If the voltage drops to a more normal level you may have a open 2ndry on the rf coil or bad ground.

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!
