M2X

This pair of M2 clone cicuit boards, use the same circuit as the Nelson Pass / First Watt M2 amplifier. However, the first "buffer" stage of amplification has been placed on a removable daughter board, making it extremely easy to swap-in different first stage circuits. A total of five first stage circuit designs are provided, and naturally one of them is the Nelson Pass / First Watt original. The product package consists of twelve PCBs: two amplifier main boards, and five stereo pairs of daughter boards. Read the M2X thread on diyAudio to learn more and join in the discussion. Board Dimensions - 25.5cm X 5.5cm. MOSFET spacing - 12cm CIRCUIT DESIGN The M2x is a Push-Pull Class A amplifier circuit, with zero global feedback. It consists of 3 stages: an input buffer circuit (on a daughter card), followed by a passive auto-transformer for voltage gain, and finally a Class A MOSFET push pull output buffer. The sound of the M2x, as Nelson Pass puts it, is "relaxed and lively."Five different
