  The Simplest Amplifier Circuit Diagram May 14, 2013  By  Øyvind Nydal Dahl   143 Comments I have been looking for a good stereo amplifier circuit diagram for a long time. I am not a HiFi geek, I just wanted to build a simple stereo amplifier that could drive some speakers for my desktop computer. All the schematic diagrams that I could find seemed to involve lots of hard-to-find components or you had to use it together with a pre-amplifier or some other amplifier stage. It was always something that made me hesitate. But recently I found this awesome little chip called TEA2025! You only need a few capacitors to make a decent stereo amplifier out of it. It is so simple to build that I put it together on a stripboard in just a few hours. 2.5W * 2 Stereo Amplifier The amplifier circuit diagram shows a 2.5W * 2 stereo amplifier. You can also make a 5W mono amplifier out of it. (Check out the  TEA2025 datasheet  for more information on that) On the input side, you should use a dual potenti
