AB Transistor Audio Power Amplifier

Posted on Feb 4, 2014

This is a class AB transistor power amplifier. It is a simple amplifier to build, uses standard parts and is stable and reliable. The entire circuit utilizes commonly available components and may be simply built over a general-purpose board. But this amplifier has very good sound quality. There are eleven transistors, including four in the output s
