audioguru Posted July 8, 2005 Report Share Posted July 8, 2005 Hi Ta,You have the collector and emitter of Q2 reversed. Its collector should connect to the positive unregulated 31.8V supply. Q2 might be destroyed since it had a high power in its base-emitter junction that isn't designed to handle power. U2 also might be destroyed since it probably got too hot feeding a high current to the backwards Q2. >:( Quote Link to comment Share on other sites More sharing options...
