LGTM, but on Slack you were saying you had two boards, are you sure you'll be able to fit them into your $100, since this is $47 and then shipping and taxes will probably bring this to ~$60?

Regardless, the design looks great to me, and is definitely the first amplifier OnBoard! Please keep #scrapbook/#onboard updated on your progress!

I have kind of given up on the dual board designs due to cost reasons, the subwoofer board would be even more expensive than this because it needs extra components. Thanks though!
