I had an odd model 91 many yrs ago. i don't remember the chassis code but it was from a chairside set. The way to tell is that the dial is printed upside down.
Looks like there's only a few differences to sort. One band or two, p# of power transformer (this will determent if it uses 1 or 2 spkrs), and tone control circuit. The early model 16 were setup the same way. First version had just a treble cut and then a little later there was treble cut and base boost. This is the same on the two versions on the 91's.
Oh another thing to bear in mind is that the 91 is the model 90 2.0 (better version of the 90) using the brand new 6.3v indirectly heated tubes. Don't get too bound up in the minutia gotta look at the big picture.

Terry is right.
It appears that Philco did not publish service info for Model 91 other than Codes 121/221 and Codes 126/226.
Code 121/221 is covered in Bulletin 129.
https://philcoradio.com/library/download...%20129.pdf
Code 126/226 (and the early model 14 chairside) may be found in Bulletin 129-B.
https://philcoradio.com/library/download...20129B.pdf
What was in Bulletin 129-A?
As no Bulletin 129-A has been found by any of us here, this information is not known at present.
Nevertheless, the above Bulletins should be sufficient to service the set. I expect your 91 Code 125 would be very similar to the 91 Code 126 data in Bulletin 129-B.
