The pinch may work but it works best with around 190. if its too high it just wont work at all, turning the pinch knob does nothing much at all. Just try it. I cant remember the highest I've had in Q2 but it wasnt like 600 or anything and the pinch wouldnt work. It will work with 200/210 so you may...

Hi!
Should this power transformer work for this project?
