Bought three of these to replace OEM parts in a lab-grade power supply that had experienced some kind of mechanical shock that destroyed the originals. These new units have a good, solid feel, with enough smooth adjustment resistance to minimize accidental displacement. The power supply now fully meets original specifications related to control features. Was able to put a multi-hundred-dollar power supply back to work for just a few bucks and a bit of my time. Great deal! These pots should work just fine in new design, too.
