Welcome. This is not the original page when I tried the M1.0t mkII but the testimonials peaked my interest several years ago. I remember reading Rich's challenge that if you didn't like the modded M1.0t or M500t after purchasing one from him, he'd give you a refund plus $50. I figured I would try one and then make $50 when I returned it. I got hooked and now have 4 of the M1.0t mkII opt002 and a M500t mkII. The circuit design used to be on this site: http://www.carvermk2.com/default.htm
