Hi
ooooooooooooh
I Myself found the answer and this is the greatest exprience in my life
I 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
