Does anybody have a schematic of anything similar to the hamptone motor controller or Carribean Controls motor boards? I just picked up a Leslie 45 (one speed only, no chorus.)

I'd buy the Hamptone or Carribe board if I had an extra $250, but the Poorman project has sapped all my spare change!!!! They can provide a slow speed around 45 rpm using just the single motors in the leslie.

What I need is a basically a pulse width modulated  AC (not DC) motor speed control with no crossover distortion. I figure somebody here has pondered this before.  Any schematics or even etched boards available???  I've been Googling all day and seen all kinds of controllers, but most are DC or 3 phase AC.

Any help out there? PRR? CJ? Doug?

I have an 825, which has 2 speeds.  The schematic is straight forward. Click on the model you have, or check out the 825. 

Good luck.
