This is a basic high power audio amplifier constructed by Bob Cordell.
Understanding this audio power amplifier sets the ground for understanding high power, transistor based audio amplifiers. – That is my experience.
In his book ‘Designing Audio Power Amplifiers’ you will find detailed explanations on how the various parts of it work. – Very much recommended for beginners.

Note: I am not affiliated with the author or the book in any way. I share this as I find the schematic and the book useful for getting into transistor based audio amplifiers. – Why buy finished products, if so much can be learned and achieved with simple components and a little DIY.
