Review on Precision Multi Turn Wirewound Potentiometer With A03 Knob (2Pcs) - 3590S Rotary Potentiometer 1K Ohm, 10-Turn Wire Wound - 3590S-2-102L by Chris Benton

These were installed in a bench power supply to get a "fine" control of voltage and current limit. They worked just fine for a while, then started to get sloppy holding their value - just like an old volume control in a vintage stereo. Inexcusable. The Chinese are incapable of making any kind of lasting electrical connections - as we've all seen it so many times before.
