Philco removed unused tube socket pins in radios like the 1937-38 radios and many more. What is the purpose of removing the pin(s)? It becomes a problem when you want to use a different tube 75 yrs later! I don't do hot-rodding as a general practice but I find I a lot of fun experimenting on my two junkers. Missing pins always require a socket replacement when updating a 6K7 with a 6SG7, a 6Q5 with a 6J7, or any rectifier. (yes, I know the 6Q5 and 6J7 are completely different tubes but they are both detectors.)
