Give this a try http://www.audiophool.com/Philco.html
Scroll down to 1941 and click on 41-295 This copy is much cleaner than the NA.
I would think that if you got the caps individually it would be less than $100. Just as a
rough estimation figure $1 ea for the mylars and $2 for ea electrolytic. That will give
you an idea of cost.
If you have nothing be time on your hands here's a quick rundown on a 41-300
I did last fall. It's pretty much the same chassis.
Common issues w/these chassis.
Open primary on output transformer. Would measure the resistance of the primary
should several hundred ohms. This can be accomplished be measuring the resistance
from pin 2 to pin 3 on both 42 tube's sockets
Faulty rubber wiring. Stop by Radiodaze and pick up their selection of multi color wire.
It's abt $20 but you get 8 or 9 spools for 600v plastic covered wire.
Bad off/on switch. It's part of the push button assy and is riveted on. It takes latching
push button sw to replace it.
If you have to service the volume or tone control be careful. These are somewhat
unique in that the shaft has the gear that's spot welded on to it. Short of having a
donor set I don't know if are any replacements.

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!
