Design a 70W Class AB audio power amplifier using ThermalTrak transistors

This video shows the details how a 70W Class AB audio power amplifier is designed. The structure of the power amplifier is divided into 6 sections, namely (1) input filter, (2) input stage, (3) voltage amplifying stage, (4) output stage, (5) output filter, and (6) feedback network. Each of these sections are discussed and examples are given.
