VPI Classic

I recently purchased a VPI Classic and a Benz Micro Gullwing SLR. I am having a problem with the tonearm. When I play a record the tonearm wobbles back and forth. I had my dealer look at it, and they are not sure what is causing this problem. We looked at two other VPI's and they looked rock solid while playing compared to mine. I have tried calling VPI numerous times to see what they have to say regarding this issue, but have not been able to get through to them on the phone.

I have tried adjusting VTF from 1.9 to 2.1 with no change to the wobble. I have tried adjusting the Azimuth numerous time, and it still wobbles. Does anyone else have this issue? Is this normal? This is my first unipivot, so I am not sure if this is typical.

Agree with Stringreen, wobbling is most likely caused by the cartridge picking up a signal at it's resonant frequency. That may be the motor, belt, bearing or some external source - or perhaps the cartridge is faulty? Have you tried another?

If the table seems to be running smoothly (motor not excessively vibrating etc) I'd try a different cartridge first.
