I had an issue with a loud hum only muted with the Master Volume knob or the base knob. After performing an annual maintenance procedure, hum still existed. Then I removed all fuses replacing them one at a time while turning amp on after each tube. Found the culprit. The middle pre-amp fuse. I love my Dr Z. I missed it when the amp was down. Thanks for being here for advice.

Well, I don't know if it's really fixed. I think you should send the amp to me and I'll take a look. I should have it back to you in two or three years.
