41-285 troubleshooting help
#9

Ok so here is the problem. You have no screen grid voltage on your IF amp tubes and I'll bet you don't have any plate voltage on the oscillator. Check #28 18K resistor (open) and #27 8ufd cap. (shorted). Should have about 75 to 120vdc on pin 3.

btw if #27is in backwards it will act like a short. +side goes
to the resistor. - side goes to the chassis

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!
