Subject: Re: [motm] 410 HELP!!!

From: Nathan Hunsicker <nate@...>
Date: 2000-04-28

Also, could I have done any damage to the op amp by running it backwards?
(it was only for 2 or so minutes) If I damaged it, is it any different
thana standard off-the-shelf TL074? And just a curiosity question, what are
the vactrol units actally designed to do? some sort of LED driver? -Nate
