I have this power supply we stripped out of a pc we're junking. It
has a 12V 10A section. I would like to use it as a 12V bench supply
for testing and running equipment.

It's amazing what you can find with Google:

Thanks a lot for finding this for me! I really appreciate it. Lenny.

You can convert your AT or ATX PSU to a tightly regulated 13.8V supply
by changing the +12V sense resistor and removing the +5V sense
resistor. You may also need to modify the overvoltage sense zeners, or
whatever circuit is used to monitor this condition.
