Seeking A Schematic, Parts List, And Capacitor Identification For A 1931 Philco 90 - Tonym4704 - 06-26-2025
Hello Everyone,
I have a 1931 Philco Model 90 radio with the single #47 tube and I am looking for a clear readable schematic, parts list, and capacitor identification for it. All copies that I have found online are very difficult to read. I would appreciate it if someone would send readable copies of all the information for this radio.
I understand that there were mistakes made on the Philco literature regarding capacitors cans #24 and #30. The correct numbers that I have are three 0.25uf capacitors in can #24 and in can #30 the three capacitor values are 0.1, 0.25, and 1.0. These three values are not marked on the schematic. I need a wiring diagram showing where these three capacitors are located. Thank you.
Paul

This is from Beitmans I do not have the reference for the parts list. David

Hi, this is right from the Philco Library located on this site! Has a parts list too.

the link to the annotated schematic that Ron Ramirez posted many years ago has the various capacitance values noted on the schematic. Its also found in our on line library:
