What is Error Correction in Voltage Amplifiers about?

This document summarizes the design of an audio power amplifier with error correction. It describes adding error correction to the voltage amplifier stage by inserting an attenuator in the feedback loop to set the open loop gain close to the desired closed loop gain of 20. This limits signal levels in the error correction circuitry. An implementation is provided using simple transistor circuits to achieve a gain of 20 for the voltage amplifier stage, followed by an emitter follower to drive the output stage
