F6 biasing help


2012-07-29 10:32 pm
I could use some guidance/help getting one of the channels in my F6 to work.
The B channel is the first one that I powered up, and I am able to bias it with no problem, however the A channel/board is giving me problems. The more positive the bias goes the more negative the offset goes. Can only get to .10 vdc on the bias before I run out of adjustment on the offset pot. Thanks.
