hello:
I was biasing my new ab763 clone project and i discoverd at nine or ten on the volume that the amp would cut out and make a scratchy like distorted sound. The biasing current increased to -56 ma as well. The biasing current i was setting it too was 32ma, i'm using Tung-sol 6l6gc-str. Would there be a standard fix for this situation.
Maybe overdrive is causing the output tubes to go into grid blocking after being over driven, the signal causing a temporary bias shift?
could that be the problem? what would have to be done fix that?
I found this link but not sure if this is my root problem?
Blocking Distortion
thanks for the help !
