Abstract
An electronic Class B master power amplifier is cascaded with a like slave Class B electronic power amplifier between ground and an output terminal to which the output of the slave amplifier is connected. A first pair of D.C. sources deliver potentials of magnitude V.sub.ss but opposite polarity to the master power amplifier and each have a reference terminal connected to ground. A second pair of D.C. sources deliver potentials of magnitude V.sub.ss but opposite polarity to the slave power amplifier, and each have a reference terminal connected to the outupt of the master amplifier. A common input signal to be amplified is delivered to the inputs of the master and slave amplifiers.
