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.
