Here is an update:
I finally got the new electrolytic capacitors installed correctly and the radio appeared dead. No tube filaments or anything. So I started testing the tubes just to be sure of the quality and see if maybe a filament had opened up. When I tested the rectifier tube (25Z5) I found out that one side had shorted. When I tested the 25Z5 only one filament side would light and it would be super bright!
I managed to find another 25Z5 tube laying around and tested it. It had no shorts, but measured bad. I went ahead and substituted it into the radio and the filaments light once again! Yay!
With the new rectifier tube I measured plate voltage on the 43 tube with no issues except I had 0 plate voltage.
Tonight I am hoping to get some more testing done and figure out why I have 0 plate volts.
Thank you guys for reading my crazy posts! 8)
