In order to improve the efficiency of the power amplifier and reduce the distortion, we usually use the type B push-pull power amplifier typical circuit. Features of the type B push-pull power amplifier typical circuit is: the static working point is in the starting part of the characteristic curve. The typical circuit of the type B push-pull power amplifier typical circuit is as shown in the figure. From the circuit structure we know it is the symmetrical circuit which is composed of two unilateral power amplifier circuits. T1 is the input transformer which has the center tap in the secondary winding; T2 is the output transformer which has the center tap in the primary winding; VT1 and VT2 are the transistors which have the same parameters, and they can use the power amplifier geminating tube.
