PCT/US91/01711 ABSTRACT OF THE DISCLOSURE A power amplifier provided with overload protection responsive to the impedance of a load falling below a threshold value having a pair of power output devices (28,30) connected to the load and driven through a balanced operational amplifier (14) and transistor couplers (44,46). The operational amplifier (14) has opposed voltage supply inputs (20,24) and each is connected through a first resistor (22,26) to a voltage source (+V1,-V1) and to the load through a pair of diodes (58,64,62,76) connected in series opposition and a second resistor (66), and the junction between the diodes is connected to the base of the transistor couplers (44,46). A fault condition causes current to flow through the diodes (58,64,62,76) lowering the potentials of the voltage supply inputs (20,24) and the bias on the transistor couplers (44,46).
