Looking for advice.
I'm working on what I believe is a Philco 46-250 Code 125. That's whats on the cabinet label and the chassis. The schematics I found online are labeled as such. A couple of the tubes didn't match the schematic, but I understand that wasn't unusual post-war and the the rectifier and output tubes were replaced with equivalent tubes with different bases.
BUT there are other big differences when I looked under the chassis.

The terminal strip the top arrow points at doesn't exist in the schematics I have. And while the schematics called for a twin 20 mfd filter cap, the radio I have had ENTIRELY different values. The Twin cap was a 50(red)/30(blue) and there was an entirely different (and unlisted) cap between the two arrows (a 40 mfd from the #1 pin of the 7C6 to the terminal strip.

I'm sort of at a loss here......
