I have it printed out and some of it helped me to get the system working as well as it is.

I think the trouble is that the main gears/servo motor are mounted to a flimsy plate which isn't very solidly located in the housing. Add to this the fact that the feedback potentiometer is screwed to a separate plastic part and the valve is in another part underneath all that.

It's like a sandwich sandwich with extra sandwich...

Mine is cracked and I think it has the parts locations all screwed up and the servo is dragging. It works but when it gets hot it overloads the servo motor Just a little drag will overheat the amp pretty well.
