Geez this radio is turning out to be a pain in the butt, because I have to put the radio in the cabinet to test it (the antenna is in the cabinet and the radio won't work without that antenna attached to it) and the speaker is too big for me to take out of the cabinet and plop it on my bench next to the radio, so I have to keep removing and installing the radio from the cabinet to do all of these tests.

So what are you thinking may have happened if you don't mind me asking?

Also I rechecked the radio and it is indeed dead silent except for the popping noise it makes when changing the band switch, there is absolutely nothing on the radio reception wise when tuning through the dial not even a little bit of static or hiss.

I also checked all of the tubes and they all tested fine (they are all the original Zenith branded Tubes to this radio except for the 6A8 tube and the 5Y4 Rectifier tube which are RCA and GE Branded tubes respectively.)
