I've got a Philco 37-630T. The schematic calls for the rectifier tube to be a 5Y4G. When I got the radio, someone had subbed a 5Y3, and it was dead.

Scrounging through my small tube stash, all I've got are 5Y3 tubes.... Online research shows these tubes(5Y4G and 5Y3) to be identical. Is that correct, or should I buy a 5Y4? I just finished this chassis and it plays beautifully with a good 5Y3, but I don't want to damage anything.
