I was trying to help a friend with his mill. He apparently left his mill on at the potentiometer and it looks like something got damaged. I converted mine a year ago and cant find my old board. I was thinking that someone else out there that has coinverted the power supply might have one sitting on the shelf they might want to sell. LMS has them but more that he can afford right now. If anyone wants to part with one let me know and maybe we can work something out.
