Well I got it working off of rectified mains ac. Does anyone know where I can get high value potentiometers, (preferably above 2M)

Historically 2Meg was probably the highest common value, and pots generally seem pretty scarce these days - at one time there were hundreds of different shapes, sizes and values - now it's pretty hard to find one you want. A pot we use (only 4.7K) we have to import from the USA.
