A transistor amplifier having a push-pull transistor driver stage and a push-pull transistor output stage operatively coupled thereto in which the transistors of the driver stage are biased for class B operation and the transistors of the output stage are biased to approximately collector current cutoff when in a quiescent condition generally corresponding to class B operation, the collector current of the driver stage, in the presence of a signal, being utilized to derive a bias voltage applied to the transistors of the output stage as a forward bias, whereby collector current in such stage flows substantially continuously during a complete electrical cycle of such signal, corresponding to class A operation.
