From: David VanHorn > LM-12 :) The thought had crossed my mind. Maybe four of them giving two bridged outputs for a special application. Mostly I only want maybe 10 or 20 watts intermittant, I really don't want to build a buffer output stage as it would have no overload protection and ideally I want short to ground and short to negative rail protection and thermal shutdown. L165 works great once I get round that minimum gain restriction but it's a pain. Oliver. -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
