This particular circuit is called a “class B,” push-pull circuit. Most audio “ power ” amplifiers use a class B configuration, where one transistor provides power to the load during one-half of the waveform cycle (it pushes) and a second transistor provides power to the load for the other half of the cycle (it pulls ).

Class B Amplifier . The Class B amplifier is a bit different from the Class A. It is created using two active devices which conduct half of the actual cycle, ie 180 degrees of the cycle. Two devices provide combined current drive for the load. In the above image, an Ideal Class B amplifier configuration has been shown.

Amplifier analysis shows that a Class B amplifier has a no-feedback distortion of about 33% and a Class A amplifier has a no-feedback distortion of about 8% and sound better than Class B. Most of the Class B distortion comes from the use of the output transistors as rectifiers to separate the plus and minus halves of the signal as well as then amplifying those halves separately …

Class B amplifiers are much more efficient than Class A amps — 50% or so — but produce distortion as the two transistors switch on and off. This "crossover distortion" is so bad that very few if any manufacturers offer or produce an amplifier of pure Class B design.
