For the most part, I used the same colors for the new wires to match the original colors of the old wires.

Philco didn't always follow the RMA color code in their wiring, although they claimed that they did so in the May 1934 issue of Philco Serviceman. Chuck wrote about it 10 years ago at the other forum.

So most if not all of the filament wires are red; B+ is white or yellow; black is ground for the most part.
