Op Amp?

Would a short in the Green Bean circuit necessarily fry the op amp? I don't want to risk frying another one if it is the case.

Thanks.

P.S. Sorry for being almost too vague!

anything is possible but it seems unlikely. opamps are usually fairly resistant to reasonable voltages applied to the wrong pin, but they're not perfect. obviously they won't work (garbage in = garbage out), but aren't usually damaged.

every once in a while, you might get an opamp that's just DOA, i remember getting a new but broken u741 opamp once a couple years ago.

Thanks Misha,
   I figured it out....In mistakenly changing things at the very last minute, I was able to unleash not 1 but 4 different shorts which disabled the whole thing except the bypassed signal. I was able to trace it up and fix the shorts...everything's is ok now. Ah, and the op amp is also ok.

Thanks for the help!
