I've done a little bit of testing to see why I'm not getting any audio. I bugged the connections for the phon pushbutton and that all looks good. I'm wondering if I have a bad 7X7 or 7R7 tube. I get no popping when I change the bandswitch...seems like I should at least get that. Other than checking continuity on the filament pins I have no way of testing the tubes. Any suggestions? It looks like I can get the 7X7 and 7R7 from Tube World for about $10 plus shipping. Seems reasonable to me. I can get all the tubes for the radio except the 5Y3GT (already got one of them) and the 6V6GT output tubes (I think they are good) for about $41.
