1930 Philco 20B Cathedrals
#17

I just rebuilt the big can capacitor. It went fairly smoothly for my 1st time doing one of these.  Icon_thumbup

The concern I have is there was a noticeable amount of tar that had leaked out onto the top of the chassis. I'm hoping it came from the cap can, and not the main transformer.  Icon_eek
I was able to clean it up.  Icon_biggrin
Does anyone have the ohm readings for the various windings on this transformer, so I can check if they are all good?
It's not indicated on any of the paperwork I have.
Here's the schematic for reference.

Any help or tips welcome and appreciated.  Icon_thumbup
