ABSTRACT:
A modified connection of elements in a push-pull transistor amplifier with driver circuitry providing over-current protection, which amplifier has previously been described by the present inventor in U.S. Pat. No. 3,855,540, increases the current gain through the push-pull transistor amplifier by a factor equal to the common-emitter forward current gain (h.sub.fe) of a transistor.
