Hallicrafters S53-A
#15

Go over to C37c (last 10mf filter) and disconnect wires from the terminal except for the 1K resistor. Check the voltage at C37c w/those other wires disconnected. Should see abt 200vdc there. If so then connect the disconnected wires one by one measuring the voltage each time you reconnect one to see which wire causes the voltage drop. This will sort which section needs going over, the osc, the 6SC7 audio stage, or the mixer screen grid circuit.

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!
