I once worked at a place that had a piece of equipment that still had one of the old analog drives and a few operators would complain and complain until they found an electrician to adjust it and then it would run like crap until we hooked up a scope to it to fix it. So I told one of the senor electricians to mount a potentiometer to the panel and run the wires to ground and just tell everyone to use that to make adjustments. Worked great for years.

Nothing to be ashamed of. Happens to one in five men.
