Following up on a prior thread, I checked my 42-380 chassis and instead of a 80 tube as a rectifier, it has a 6X5. Checked the tube layout sticker on the cabinet and sure enough, it has the 6X5 listed. I know this tube all too well as my Zenith 12-S-475 had two of these and they blew the power transformer. As I read up on these, the less I liked them, so I will take everybody's advice and replace it with silicon diodes. In the meantime I did want to confirm they were used on the 42-380. They probably used it after Pearl Harbor as production wound down.
