Thanks for the tip FastDoc!
Ill try in Yamaha store.
I just wanna have one of these in spare...im always suspicious on these vacuum things
Although its good i took it apart,someone took it apart before i bought it and the little spring on top of the needle droped down it the vacuum piston and jamed there. I dont know how it worked without that on the needle :?
I mounted it back on top of the needle before i put everything together.
Thanks for the fast answer!
