Abstract
The invention provides a class BC power amplifier which permits control by a circuit with a transistor, which circuit, besides its control functions, effects also a protection of the end stage from transient processes caused by the inductive character of the load. The efficiency of the amplifier is not lowered, but it remains sufficiently high and corresponds to the class BC. The use of an output transformer is not obligatory.
