I can try. Lucky for me my brother is an electronic engineer. He designed and built the speed control for me. It is programmed to created the two 90 degree offset sine waves at any desired frequency. Voltage is also adjustable and it has a start up function where it produces maximum power to get the platter going. No push start needed here. The amp modules are basic LM3886 based amps, built in to the design.
Thanks for the explanation.
I was hoping that if we could get a schematic or PCB!
I think that there are a lot people with AC motor turntables that would be interested in this.

Very good try!Nice clean cuts.
A bit like a Bauhaus statement.
Question about these thick acrylic platters:Can they be painted?
Schematic for the motor PS+control?
