Philco 37-3640 / 37-640 questions
#4

Hi and welcome,
>Is it the correct voltage polarity?
In this situation the + side is connected to the chassis and the - goes to the center tap of the HV winding on the power transformer.
I'll mention if you have an electrolytic capacitor that has been connected backwards do not reuse it, chuck it it's shorted.

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!
