The applications note referenced earlier had High-end pretentions and the National chips came highly regarded. Before designing a MC stage I wanted a reference that was relatively current and accurate. ![]() This MC amp was actually a departure for me. I think the problem with an MC design is at the quiet end of the spectrum, I debated placing a FET buffer before the National chip to bring up the quieter end of the spectrum so that the chip would have an easier time of it. I've used op-amps in power supplies and as servos and quite often as part of my real work, but for audio I've always stuck with discrete transistor designs. ![]()
