Hi Aron, Glad the thoughts helped you out! And that your oscillator is back online... Reminds of one of my favorite sayings, 'It is not how easy we make the hard problems but how hard we make the easy ones!9; I am so guilty of failing that test, all too often....
Now I have to get cranked up on a problem Quasimodo is having. (one might think, erroneously, that I'm lacking projects.....)

Hugh,

It's fixed!!!! First off the first op amp was dead. (IC801). Secondly while removing the op amp the top trace (double sided board) was broken from 805->pin 1.
That was it. Got oscillation now.

THANKS!

Aron

p.s. thanks for reminding me of basically troubleshooting - continuity test and measurements!
