Building the Simplest, Best Sounding, Yet Most Inefficient Audio Amp!
In this project I will be showing you how to create a class A audio amp. The great thing about such amps is that they only require a few components and sound awesome. On the other hand though, their efficiency is not that great. But since I will be creating this amp for a smartphone with a USB Type-C port for powering the amp, it should be just fine. So let me show you how to calculate a design for such an amp and how to build it! Let's get started!
Watch the Video!
The video gives you pretty much all the general information when it comes to building a class A audio amp. During the next steps though, I will present you some additional details.
