Title
ELENCO XP-720K Voltage Control Potentiometers Replacement
Introduction
The power supply works as the package is designed and built but I found the adjustable voltage potentiometers to be very touchy as to getting to an exact voltage desired and a bump of the knob would through that off. While not a major problem, I found it frustrating when wanting the positive and negative voltages to match for a project.
