I want to add variable speed control to my Sankyo Sound 762 movie projecto. I have a CCM5D 6 to 30VDC, en I will appreciate some advise about how to connect it, and will be grat to have the electronic schematic.

That projector definitely uses dc motor,so there must be speed regulation circuitry somewhere inside.
On that speed regulation board there must be 2 potentiometers for fine tuning the 18/24 fps speed. You'll need insulated screwdriver to adjust that.

All in all,that means you should really don't need to add anything to make it "adjustable". [Wink]

Thank you very much Nantawat. I founded the two little pots and it and it worked very good. Thank you again.
