I've done that before, with scraped leads, and meter or scope probes. I
also had a board that worked for about a week and a half, then a short
apeared and fried a few chips. It could be from a small metal burr that
almost was shorted before (probably not on ken's boards), or from some
solder that wasn't quite shorted but is now.

If the IC let out smoke, replace it. I've noticed that sometimes they
will still heat up after that and sometimes not.

blowing the opamp does sound like a power problem.
