Hi Kevin, Do you have a filter capacitor on the bridge rectfier? You need one. Also, wallwarts are meant to run hot whenever close to ratings. My rule of thumb, if you smell it when you enter the room, it's too hot, otherwise it's OK :-) Cheers, Bob -- http://www.piclist.com hint: The PICList is archived three different ways.
