Design and Construction of Class AB Audio Amplifier
https://ukdiss.com/examples/class-ab-audio-amplifier.php
For an excessive period, Class A and Class AB were the only amplifier classes that are compatible with high quality audio systems. This is because valves were the single active device, and Class B amplifiers generated masses of distortion which made them barely acceptable for numerous purposes. Construction of Class AB am…

ing on the design. Amplifiers for hearing aids and small radios have to operate from extremely small batteries. If the battery of such a unit is to have a reasonable life the design must be efficient and the earpiece must match the output impedance. It is also important that the amplifier chosen for a parti-cular application be no more than what is required
