Hi Bill and Welcome!
Here is the diagram for your set: http://www.nostalgiaair.org/PagesByModel...013233.pdf
You will note two filters. One (#45) goes from the 5Y4 filament to the high voltage center tap. The other (12a) goes from the filter choke to chaiss ground. 20MFD@ 450v will work FB for both. As Ron recommended replace all of the caps electrolytic and paper. If not you will be wasting a lot of time troubleshooting to find that the unreplaced caps are the problem. DON"T CLEAN the DIAL the print will come off. Don't ask how I know.

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 it!
