Shahriar Posted September 30, 2004 Author Report Share Posted September 30, 2004 Hi oooooooooooohI Myself found the answer and this is the greatest exprience in my lifeI had forgotton to solder one of the jumpers whic was related to -Vee Net,so we take this result that if you forget to solder -Vee then the NE5532 gets hot and the device do NOT work properly ;D so remember to count the jumpers when you finished soldering, but I expected Distortion in case the Lack of -Vee but why the things i said above happened?Anyway I am very happy Quote Link to comment Share on other sites More sharing options...
