M2XThe M2x is based upon 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. Read the M2X thread on diyAudio to learn more and join in the discussion. The M2x is a Push Pull Class

Among the appreciations of DIYers is stuff that works simply

These boards are the newest revision

Faceplate: 90x24x10

Nelson's Bipolar Power Supply is the least expensive and easiest to build

and when the supply is switched on

match those parts to PCB locations based on the silkscreen

The M2x is based upon the Nelson Pass / First Watt M2 amplifier

guitar effects

Compared to the previous power supply

and plate supply voltages can be as low as 5V

please adjust the bias current to a level suitable for your environment and/or increase the heatsinking

The diyAudio "Universal Mounting Specification" (UMS) is a common mounting pattern between the amplifier PCB and the heatsinks
