A question about tubes: My Philco 42-1009 needs a 5Y4 tube. I have some 5Y3's, and it looks like i can use one if pins 7/2 3/4 and 5/6 are swapped around. Does anybody know why there are rare tubes like the 5Y4 that are simply variations of popular types???
It's kind of hard to figure out what the manufactures and engineers were thinking about when they do that. My Philco 37-116 uses a 5U4, where my 38-116 uses a 5X4. The only difference is the pin-out.
Zenith used a tube socket that didn't have the contacts for a 5Y3. Maybe your Philco does. If so, rewire it.
