ABSTRACT:
A pair of complementary output transistors having common connected emitters and a primary winding of a transformer in each of the collector circuits, said transistors being biased in class AB operation with a drive transistor connected to the base thereof and a feedback circuit, including both AC and DC, connected from the common emitters to the input of the drive transistor so that the quiescent current of the amplifier is very low and the output impedance is high.
