Great boards. one thing that would help would be a v3 build guide. Its a little confusing that the boards are v3 and the guide is based on v2. It would be easy to start stuffing before realizing the part designation is different between the 2 versions.
Overall quality is excellent though.
So glad they have a F 5 kit now. Great service and great products. I built the amp camp amp before doing the F5. The ACA sounds great, best amp I've ever owned. I have owned alot of amps tube and transistor and this is my favorite. I run 88 db speakers and I have plenty of power with only 6 watts class A. good stuff
