what are the pros and cons of using a IC based biased controller like stated in the bob cordell book? will it reduce the distortion to a considerable level?
Is there anyway that we can switch on an off the transistors prior the input signal so that the distortion can be reduced and the amp gets into class A mode in terms of distortion with little heat dissipation.
something like this with an offset like an envelope
