Mini6 Amplifier

I was a bit bored a couple of weeks ago so I decided to design a very simple discrete amplifier rated for 6W/channel just to make sure it would’t oscillate and be more confident to build bigger ones.

As you can see it’s a fairly simple design with a op-amp pre-amplifier and a discrete power amplifier. Building it was extremely simple, the difficult part is always mounting all the panel components and wiring everything.

A while ago I built a program called build-bom to help me quickly find the component values when assembling a board. It’s a great use for a old EeePC that you may have laying around.

One thing that you may have noticed is that I’ve used canned transistors instead of your typical plastic TO-92. The only reason I did this was because they looked cool and I have a bunch laying around.
