audio amp

Over the weekend I put together an audio amp using a schematic from N6QW. It is from his simpleceiver project.

Since my bitx project fizzled out ( I will try to get it working one day.) I figured I would start on another transceiver in my free time.

I’ve got some packaged mixers instead of using plain diodes and I may buy a crystal filter instead of trying to make one myself. That may make things easier this time around.

Anyway, here is the schematic:


I used a drill press to make islands and I glued the chips down dead bug style. The amp works great. Its nice and powerful.
