hey, you have had some bad luck there with your kit… really sorry to hear it… i have experienced many similar issues and i am interested in your ot headphone out problem. i posted a way to test the problem in the headphone crackling thread but no responses so i wonder if you have tried this method… because it fixed mine… i dont believe that re soldering the output jack is the issue. the problem is relating to the digital part of the machine as the noise produced is not analogue circuit distortion. it sounds very digital in nature… anyway good luck.
