[QUOTE=DavGoodlin;3034663]I have a Philco 42-1009 that needs a 5Y4. No way do I have one! A quick check of my 1953 GE tube book reveals that the filament current and forward current is same as a 5Y3, so I will move two wires on the socket, because that's the ONLY difference.

In the 1938 model Philco's, the rectifier socket was on top of the transformer. It made the change a lot harder.
