A circuit for a selective push-pull amplifier having amplifier triple poles of the same polarity which simultaneously produces high efficiency and low nonlinear distortions. The circuit has control electrodes controlled by out-of-phase control voltages and an output inductance having a center tap which produces a magnetic combination of output currents of the amplifier triple poles. The output electrodes of each triple pole is connected to an output inductance through a transformer having three windings. Two oppositely polarity windings connect the output of the triple poles to the output inductance while the third winding is connected to provide a series resonant circuit.
