Does anyone have a link or other documentation that lists the values of all the IF transformers used by Philco?  I'm trying to find other chassis' that used the same 2nd IF trans as was used in the model 52 since I'm having an issue with finding a junk mod 52 that i can strip.

If that is a 52 baby grand with 175 IF, you might try a 262KC IF Meissner or Miller (plentiful ebay) as they have a broad range to get you up and running until you find 175.

I don't recommend using a 260/262 kc IF transformer.

IF transformers from Philco models 111, 112, 90 (early and middle production), 51, and 52 all use 175 kc IF transformers. Model 17 does also; however, model 17 is less common.

Oh, and the documentation you asked for does not exist. I don't think anyone has compiled a list of all Philco IF transformers, their design frequencies, and the radios using them. However, the listing I gave you above covers all Philco home sets using a 175 kc IF.
