A Class B push–pull output driver using a pair of complementary PNP and NPN bipolar junction transistors configured as emitter followers. A push–pull amplifier is a type of electronic circuit that uses a pair of active devices that alternately supply current to, or absorb current from, a connected load. This kind of amplifier can enhance ...

A shunt regulated push-pull amplifier is a Class A amplifier whose output drivers (transistors or more commonly vacuum tubes) operate in antiphase. The key design element is the output stage also serves as the phase splitter. The acronym SRPP is also used to describe a series regulated push-pull amplifier.
The data sheet information supplied by the tube manufacturers' design-centers list the typical operation of an audio output stage for a single 6V6 as producing about 5W of continuous power, and a push-pull-pair about 14W. Amplifier manufacturers soon realized that the tube was capable of being used at ratings above the recommended maximums, and ...
Push–pull power amplifier. The push–pull output circuit shown is a simplified variation of the Williamson topology, which comprises four stages: a SET input stage to buffer the input and give some voltage gain. a phase splitter, usually of the cathodyne or "concertina" type.
In the example shown, the operational amplifier is used to reduce the distortion of a push-pull pair. Operational amplifiers are differential voltage amplifiers with very high gain (sometimes modeled as infinite gain). In an ideal model, the output of the op amp is held such that both inputs of the op amp must be at exactly the same voltage.
Class-A amplifiers can be designed to have good linearity in both single ended and push-pull topologies. Amplifiers of classes AB1, AB2 and B can be linear only when a tuned tank circuit is employed, or in the push-pull topology, in which two active elements (tubes, transistors) are used to amplify positive and negative parts of the RF cycle ...
