Harmon Kardon 330b: Bias voltage locked in place.

first thought, check your meter's battery? 2nd thought, I can't really tell what you are connected to, can you test the other side of the board by locking on to the legs with j-hooks. If there are ceramic insulators on the legs that are blocking you it is ok to crush them (they will fall away), shield your eyes in case a splinter flys your way.
 
I just realized i was on the wrong resistors. There are two resistors nestled behind the ceramic ones that i have never noticed before. Went to unsolder one leg & the emitters didnt budge.... God damn. No wonder i always have bias issues with these...

Yeah there had to be a simple mistake. If you can get right on those legs you might find you are good to go.

Its such a pain in the ass to get on the legs topside without pulling the heatsinks off thats why i usually try from the bottom. But i went topside & adjusted, sure enough, got them both to 8mv. False alarm fellas, thanks anyways.
