i have the revision D board. can someone describe what to disconnect, if i want to try the amp with no negative feedback? i have it open and i just am not clever enough to figure it out...
thanks

also can anyone tell me what the function of adjustable resistors 30 and 31 are for?
in playing with the bias, no amount of turning seems to affect the DMM readings on R22...it reads about 0.450vdc(yes i tried the adjacent test point to make sure i was on the right one )...do those screws turn indefinitely or what?
this spring i smoked R17 and R26 pretty bad by using some cheap ebay tubes without a bias check. could this be my problem...?
