Brenda, I confirmed with two other tubes that the cathode current is around 22 to 23 mA. These measurements were made on my junk chassis, which has not been recapped. Since I removed the output transformer from my recapped set, I can't make measurements on that one.
I measured all the voltages that are listed on the schematic, also on the junk set, which worked for a short while before the output transformer went out.
Arran, the two transformers failed in two different radios. Just by chance I found a junk set (same chassis, different cabinet) that I fired up to make some measurements on. It wasn't that my recapped radio fried 2 transformers. It was very odd that both failed in the same way, though.
