The purpose of the class A bias is to make the amplifier relatively free from noise by making the signal waveform out of the region between 0v to 0.6v where the transistor’s input characteristic is non-linear. Class A amplifier design produces a good linear amplifier, but most of the power produced by the amplifier goes wastage in the form of heat.

The advantages of Class A amplifiers are no crossover distortion and switching distortion, and the harmonic components are mainly even harmonics. The circuit is simple, frequency loan, small instant distortion. In the sense of hearing, the bass is thick, the midrange is soft and warm, the treble is clear and sharp, and the layering is good.
