The value for those bypass caps isn't particularly critical. Just for convenience I've used 4.7mf at 450dc to replace the ones in several of my large chassis Philco's. 10's or 20's are ok as they are invisible once they are charged up.
When working properly should have a good sounding set as it has the super class A push/pull triode connected 42 tubes. Good for 10w of clean audio. You my want to have a look at the interstage transformer between the 42 driver tube and the pair of 42 outputs. Not unusual for it to have an open secondary or primary.
OBTW Happy Birthday!

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.

Now I think I've got!
