Last Saturday I spent the whole afternoon cleaning the potentiometer, and playing. At first has this hisss... Then the noise seemed to have gone away, but then againg it returned ... So I kept on playing, and alittle later I posted this thread.
Yesterday (Sunday) I woke up and the first thing I did was to check it .. And it`s was O.K. It could have been the lack of use which cause the hiss (plus the dirt in it)?
GOOD lUCK
PS: Thanks a lot, Again!
