In this video, I repair a Sorensen DLM 300-2 that has a jumpy and unreliable voltage control. I replace the Bourns 3590s-291-502L potentiometer do this repair. I also modify the power supply to have banana plugs in front of it. this should be about the same for any of the Sorensen 600-watt power supplies.
