Class AB Power Amplifiers. The class AB push-pull output circuit is slightly less efficient than class B because it uses a small quiescent current flowing, to bias the transistors just above cut off as shown in Fig. 5.5.1, but the crossover distortion created by the non-linear section of the transistor’s input characteristic curve, near to cut off in class B is overcome.

A Class-AB audio amplifier involves three stages: Input stage; Voltage Amplification Stage; Output stage. And the design of each stage requires: Basic circuit theory, Transistor-based amplifier design, Filter design, And even a very basic understanding of feedback theory. So, as you can see, a Class AB audio amplifier is not a "how can I design one?" thing.
