thanks Graham. I guess with all those surface mount active devices one could easily suspect one amongst them must be a digital Devil -- but the ABS is all analog, all the time.
It's encouraging to read that despite the modifications you have already made over the stock bias supply, the ABS still gave you some improvement in sound. since the ABS eliminates DC current through the transformer core, the improved bass response to noticed is to be expected. Probably the bias voltage we apply to the grid is one of the most overlooked factors in our quest to squeeze ultimate performance from our amplifiers.
thanks for the write-up, and your well drawn out diagrams.
