It is designed to utilize Carlos' Snubberized PS. Cheers!

Helu Russ, do you have Eagle in your "Autostart"?
 I'm sure it will work, and I'm also sure that you already have etch it? On my board (wich is a 99% BrianGT copy, so thanks/sorry Brian ) I added snubberz before the big cap.http://www.ettnet.se/~tobias/diy/lm3886/3886.png Another (big) http://www.ettnet.se/~tobias/diy/lm3...3886opabuf.png Keep spitting 'em out...
