OK, so I have a question and a little update on this radio.
I was finally able to acquire a tube tester that can test the tubes that these old 1930s radios used, and I tested all of the tubes in this radio (except for two of them) and they all tested like brand new, and they are the original Coronado Branded tubes!
Now for my question and the two tubes I was unable to test.
My Tube tester I have is a Knight Model 600 Tube Tester from the 1950s, and it had listed in its tube chart a 1A4P tube, but this radio uses a 1A4 tube, which from what I can see looking through the tube data sheets online they are basically the same tube, but then there are some tube data sheets that state that they are completely different tubes.
My tube tester results seem to confirm the latter idea, because when I used the setup data from my tube tester that is for a 1A4P to try and test my 1A4 tubes they get a mediocre reading and I know that can't be the case, because the rest of my tubes in my radio test like brand new (100+) and those 1A4 tubes couldn't both be the the same amount of deadness (40) and the rest be like brand new, and then have the radio working as well it does.
Anybody have any ideas as to why Knight would only list one 1A4 tube in their tester setup chart (the 1A4P) and whether or not there really is a difference between the 1A4 and the 1A4P tube?
Thanks for your help.
