What do you mean "can
't run on high power"  What happens, supply suts down?  What is the 
current rating on the original supply?  Perhaps rf getting into the 
supply and shutting it down.  If so a choke on 12 volt leads might help.
  As fr as the swithcer, I hate those things.  Perhaps choke on power 
cord, maybe.  As I mentioned on this a few days back, put a new computer 
suppoly in a broken computer and raised my background noise on 80 3 s 
units.  yech!!!!
Good luck.
