A push-pull output pair can shift in and out of its class under load. Can't this sort of problem be controlled using some type of compensation? For example, in a Class B output pair, we can design local compensation into the output stage to help improve linearity and minimize crossover.
Can't the same be done for Class A or AB? Some type of current controlling device that could, say, sample the current drawn through the output pair's emitter resistance, regulate the quiescent current, and turn on and off when the current draw is looking low?
