Sounds like bias supply failure in the AC-4. Most likely electrolytic capacitor failure.

*Hey all, I am new to the group, and would like to start off by picking the collective brain :-)) I am having trouble with my T-4XB. I was working CW with it the other day when all of a sudden, it shot a fuse. I changed out the fuse and started it back up. The new fuse didn't blow, but when the set warms up, and the tubes start to conduct, the TX/RX relay kicks in and the plate meter starts to show a lot of plate current, around .25 to .3 on the meter. The transmitter won't tune, won't key, won't do anything except light up. I did a visual check underneath, and nothing is obviously burned. or out of place. I thought it may be the 6EV7 tube associated with the relay, but I have no way of testing the one in the set, or any of the others I got with it. Anyway, I thought this may be a common problem associated with this particular set and decided to put the problem in front of the all knowing ones of the famous Drake list! Anybody got any ideas?
