essentially preceded by a driver amplifier which drives it to give high power by making its internal resistance low. Being a high current device, the power amplifier has higher distortion than voltage amplifier, and therefore, push pull circuits are used for power ... Negative feed back reduces distortion and stabilises gain, making it independent of change in characteristics of transistor or components.
