In Reply to: RE: my bias is running away on one side even with the bias backed all the way off on that side! posted by Jonesy on July 24, 2020 at 11:03:04:
I appreciate your help Jonesy; as it is probably way more than obvious by now, I don't have a very good grasp on electrical theory.
I did find in the manual this: "[. . . .] Next is an additional dual channel bias supply for the EL84 current source tubes. This is factory preset & will not need any adjustment."
Also, those diodes you identified for me which I thought were resistors, I think might be these: "The rectification is accomplished utilizing multiple solid state 3A diodes in a center tap full wave rectification."
Anyway, thanks for all your help!
