[sdiy] recommendations for bench supply?

[Dino Leone]

Thanks so much for the feedback Harry!
the MOTM supply actually has a PowerOne in it. And I think it shut 
down at least one of its outputs yesterday when I was tinkering... 
scared the sh*t out of me when some of the blinking lights in my MOTM 
and Oakley modules suddenly stopped blinking and instead froze.
That leads me to a more general question: how do op-amps, OTAs etc 
behave when suddenly one of the supply rails go to GND, but the 
second rail stays up? Can that do any damage to the parts?

Best,
Dino
