O2 is great and it is quite simple to build. There is even simpler amp called CMoy[1] which is simple enough to be first project for somebody just starting out.

I would start by taking look on some oss version[2] and order PCB from OSH Park[3]. I've built this version few years ago and it works well.

- superflyguy 8y agoI built the cmoy. It was easy. But I know nothing about how it works, and I remember reading warnings on associated web pages like "this is not a guitar amp" etc. I'm curious to know a little more about how these (amps generally) work, why they're seemingly non trivial to design at a reasonable quality level etc.
- dejv 8y agoGuitar amps are very different beasts. If you want to build something simple there is "1 watt guitar amp" project[1] with many different variations. [1] https://www.electrosmash.com/1wamp https://www.electrosmash.com/1wamp
- superflyguy 8y agoYeah thanks but it's not that I want to build a guitar amp; I'd just like to read a little about the difference between guitar and headphone amps, different design decisions for headphone amps generally, things like that.
