Put in a new tube
Put in a supposedly NOS Sylvania 50B5 (it actally tests lower on my Lafayette tester than the used Admiral tube it replaced). Initially it had more hum than the original tube. Then I noticed that the 12BE6 tube was not properly seated in its socket. Pushed it back in and most of the hum is gone. Now you have to put your next ear next to the speaker to hear the hum. Looks like I got an extra output now.
