Has anyone attempted to build the AX84 amp? I am thinking about building one and wanted some opinions on which to build.
The AX84 kits from doberman are a great way to start amp building. I started with the P1x build. It was simple enough for a first build, and it is a great way to learn.

If you want to learn more about amp building, check out the link in my sig. It'll give you an idea of how the different parts of the amp work together. It's not complete, but it could help you out.
