ABSTRACT Apparatus and method for driving a non-centertapped load such as a loudspeaker from a low voltage supply such as a single dry cell, with increased efficiency. A push-pull signal having similar polarity voltage excursions is applied to opposite terminals of the load. Alternate individual terminals of the load which are opposite to the terminals to which the non-idle phases of the push-pull signal are alternately applied are connected to a common terminal via a pair of transistors. The pair of transistors are driven by an amplified representation of the push-pull input signal. Since pulse signals are not used to drive the pair of transistors, capacitors need not be used to eliminate switching transients which would otherwise appear, and increased efficiency results.
