But what I'm not sure about is where does the power come from? Is it sinking or sourcing? Do the bob terminals directly replace the potentiometer?

Many thanks

Lee We don't have a crystal ball. you need to give a link or picture of the bob. You could put a meter on the bob terminal and see what you get.
