I've seen a few kits on the net that you can get for around a thousand dollars that are supposed to be API and Millennia copies. The circuit design looks very simple especially on the MM-990. its an epoxy molded gain circuit that needs a power supply and phantom power + a rack box. Anyway, I'm sure there are a lot of differnt kits and I was just wondering if anyone had taken the time to sit around and build one. If so, I was hoping to get some opinions and results about the whole ordeal.
