Philco 50 (early version)
#31

Anyone have a better scan of the label that goes on the Sprague electrolytics can?  I did a little photoshop on this one but the scan is still off center a bit.  When you print it and put it on a can it actually doesn't look so bad since its curved anyway but thought I'd check...and this one will be available until a better one comes along.

Thanks for this great restoration thread Bob. I just started on a Philco 50 and your detailed restoration is a great help!

Do you know the pin-outs for the bypass capacitor block (No. 15 - Part No. 03459)? The schematics I've seen (service bulletin #86, Riders, Beitman's) list values but don't label the block or the schematic.  Icon_rolleyes

I'll post some pictures from mine soon too.

Ah ha - fortunately the 'Internet Way Back' has a reference to the annotated schematic. Icon_smile

So that helps!

Great find! The cap block just had wires coming out of it as labeled on the wayback post. http://philcoradio.com/phorum/showthread...#pid111946

Hey Bob,
I have a phlico 50 that someone has tried to do a restoration.  Icon_mad  Wrong Caps & some missing, especially from the #15 Cap Can. There is no can now, which complicates things & tracing the schematic some of those caps are missing.  Icon_crazy   I know the values for the caps that were in the can.
What I would like to find out is, have you marked a schematic to show which values go to the #15 caps on the schematic?
Thanks so very much for the Help
Jason

Jason, I think this will answer your question. Ron has a number of marked up early schematics in the Tech Section.

Woohoo! Thank you so much Bob. I didn't think to check in the tech section. I am so very grateful to you for pointing me in the right direction.  Icon_biggrin
Now maybe this 50 will actually work with right caps, in the right places.   Icon_thumbup
Thanks Again!
Jason
