It appears as if there are a lot more Code 121 sets in existence than there are Code 125's. So why did Riders not draw up a set of schematics for the Code 121 sets instead of just indicating the tube changes on the Code 125 schematics ???? This problem occurs on a lot of the Philco sets during the 1940's ans 50's.
Anyway I have seen a schematic of a 48-200 Code 121 (with the 35Z5 and 50A5) somewhere in the past and my other question is: where can I find the proper Philco schematics with the Code 121 ?????
Thanks;

Hi Andy,
Rider's only printed the schematics that were submitted to them. In some cases the code change might have only been something in text. Chuck Schwark here might be the best possibility of having something that you need.
