Abstract
A power amplifier device comprises a power amplifier including an output transistor and voltage is applied to the output transistor from a source through a switching type stabilized source device. The source device produces a reference voltage equal to the sum of the output voltage of the amplifier and a constant voltage required to be impressed across the collector and emitter electrodes of the output transistor.
