Hello all, Iam new here and glad to be here. I recently retired and now have some time to get involved with restoring some of the radios that I have acquired over the last few years--first on my list is a nice Philco 40-130T. I have electronics background from years ago and Iam going to take my time and refresh my radio repair skills along the way--ok that being said, my first question is about the tube line-up in thr 40-130, the output tube is supposed to be a 7B5, but has a 7C5 in it's place--is this going to cause a problem? Iam headed off to the radio swap meet flea market here in the Seattle area tomorrow and will be looking for some tubes-so maybe on original 7B5 would be in order for the set--heck I may try to get a whole set if available
