You could have used 2 channels of the scope and used the A-B mode.

So how hard of a lesson is this? Do you know what's wrong with the scope, and how to fix it? Thanks for the information, btw.

Well, this is one of those times where you feel silly, and yet don't mind. I finally got some time to look at what happened and was grateful to find that my power bar became a sacrificial lamb, paying the penalty for my ignorance and saving the scope. I must admit I've never seen a power bar completely fry out before, but I'd rather it be that than my scope!

power supply noise
the first and only time this happened to me I was examining the noise on one rail of a power supply -- wondering how it was getting so noisy and loaded -- turns out that the scope probe was doing the damage. -- there was no isolation transformer on the supply at the time.
