So this past week I treated myself to a brand new Dynavector 10x5 cartridge and a new belt. Now the belt "rolls" and every few rotations snaps back into place causing an audible pop. It isn't slipping but rolling. It actually moves up the rotating spindle slowly then all of a sudden jumps lower causing the pop. The shop where I got this from has never heard of this and I even went to another shop with the belt to see if I could recreate the act there to no avail. This rules out the belt so I'm at a loss. Anyone? I was going to have a few friends over tomorrow for a listening session but this changes eveything.
The pulley maybe a little sticky, clean with q-tip and alcohol, put a little powder on the belt as a second fix, the Rega motor is held by rubber straps if they have moved much this could put the motor out of alignment with the platter
