Finally getting to this cathedral radio and as usual always instructive to go through and look at things closely to see where you are at. The listing did say it worked! Well, not brave enough to try it. So off looking underneath and testing resistance of all the metal stuff. Power transformer looks good, field coil looks good. E-caps have had some work in the past but still need to be changes. Checked the cadohm resistor from point to point and looked good. Decided for no real reason to test it from one end and just march down the line. When I got to the other end well, end to end measured shorted. Well that is weird, I said to my self. Who ever played with the caps in the past had really messed up. Cap 42 which should have the ground isolated and attached to the center tap was at ground! Looking closer, the little ground tab that should be in between the cardboard and the can was on the outside and grounded. It just added more capacitance to the input line and left the voltage divider for producing some negative voltages for the tubes without any filtering.
Might have worked, but I doubt well. On to working on the rest of the radio. Just fun to try to figure out what people did to the poor old radios.
Pictures as I work through the problems. With the e-caps done, might try to bring it up slowly. Just finished a new speaker to chassis wiring as it had 3 strips of zip cord. Looked ugly. Just having fun.
