Hi Todd
I don't need an automated tester for the voltage regulators. I can live with a toggle switch to change between fixed and variable regulators, and a pair of meters for volts and amps. And maybe a switchable load.
More important is the mechanism to clamp onto the leads. A heatsink clamp isn't necessary, since I won't run these at full output to test, except maybe only for a second or two. And they're thermally compensated -- you have to really work at over-currenting these devices to fry them.

After a few times of jury-rigging a test set, I'll have used up the time needed to build a jig.Jim,I see your point, of course. Since all my test equipment, leads, fixtures, etc., are always set up and ready to go, for me it's easier to test on the fly.I've been thinking about a tester for regulators all day, using an Arduino or other MCU of course. I might just mess with that idea tonight for a little change from a frustrating troubleshooting project.73,Todd
