1935 Philco Model 650 Wiring Schematic Needed (Code121) - Paul341 - 05-24-2026

Hello Everyone,
 I am searching for a wiring diagram for a 1935 Philco model 650 Code 121 radio. There are two versions of the chassis (121 & 122) and all of the information online is for the code 122 chassis. I would appreciate help in finding the correct information. Thank you.
Paul

Here is a link to the service bulletin for the 650.

I don't believe there is much difference. I have a 650X and will go check my documents. I noticed at the end of the parts list there's a few notes relating to code 122 parts numbers. This tells me that the schematic shown is for code 121.

Thank you Arran for your reply. The schematic you sent is for the code 122. It is the same as all the others I have seen online. I have both chassis code 121 and 122 and they are very different. The Philco service bulletin shows a few changes but the chassis I have is not the same at all.
