So I am back to square one. But learning (or re-learning) new things with each false assumption that I make.
So it seems that schematic I have for the radio is the wrong one. My model is a Philco 48-200 code 122, the schematic I had was for a code 121.
The other thing that I have now learned is the difference between an Octal tube and a LOCTAL tube (Thicker pins for the former, thinner pins and locking mechanism for the later).
The output tube in my radio is a 35A5, which has thicker pins (Octal). The schematic for a code 121 (not mine) shows a 50A5. This will definetly not fit since this is a loctal tube.
Question for the Phorum: Does any one have a schematic for the code 122 version of my 48-200 ? Can anyone tell me what the proper tubes would be for this radio.
