Well this is a strange but true story about a 7F8 tube on a 46-1209 and maybe this is just a fluke, I can only say what happened. On a 46-1209 that a friend of mine was restoring the 7F8 tube had 4 neatly cut tape squares on the rivet heads, since they were old one had fallen off when the chassis was being recapped. After everything was done the radio would not play, all sockets had been cleaned, tubes checked and a radio that played before service would not play after. So one last chance was to put the tape square back and the radio worked. So turn to another 46-1209, mine intermittent problem so I was talking to my friend and he told me the story of the little tape squares on the rivet heads, so what did I have to loose, I cut 4 nice little black tape squares, put them on each rivet head and no more intermittent problems. He said the squares on the other 1209 seemed to be factory original. I used the same tube, I had cleaned or re-inserted the tube many times and that did not make a difference until I put the squares on the rivet heads, after that it worked fine.
