There are several Mellotron improvement projects I've been working on.

Replacing the Mellotron power supply with a modern switching power
supply. This could potentially lighten a Mellotron by about 50
lbs, provide better motor stability and allow operation from 115 or 220
volt lines automatically. Preliminary experiments look
Replace the CMC-10 servo board with a servo controller of my own

and barely works, the later SMS servo board is good, but I think I can
do even better. Preliminary experiments look good.
