I recently puchased a Philco model 16B, that was restored . When it arrived the #5Z3 rectifier tube had come out of it's socket, and broke inside the radio during shipping. I reserched that a #80 could be replaced by a 5Z3, but it did not state the other way around. However I had an extra #80 tube for my model 20 cathedral, and put it in the 16B radio, and it plays nicely. My question is this, is it OK to do this? Will it hurt anything in the radios circuitry? Thanks very much. Glenn G
