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.

Thank you for all the advice. The table seems to be running smoothly, and I can not detect any vibration. The table is dead level, and this is the second cartridge I have tried. I was using a Benz glider for about 4 days, and it wobbled just like the Gullwing SLR. I have also tried using two different counter weights with no luck. Could it be a problem with the unipivot bearing? My dealer and I both tried calling VPI, but I have not been able to get through to them. I just get a busy signal. Im sure my dealer will be able to get through to them next week. Is anyone using a Benz Micro cartridge with their VPI? Thanks again for your help.
Well, I got a hold of VPI this morning. VPI thinks that I might need a little damping fluid and a different periphery ring. The Benz Gullwing is being effected by the stainless steel ring. Yes, I know stainless steel is supposed to be non-magnetic, but according to VPI some Benz Micro cartridges can be influenced by some of the rings they have manufactured. Some are less magnetic than others. So, they are sending me a ring from a new batch they just machined. You can see the cartridge being pulled towards the ring. Anti-skate is set correctly. So, earlier today I added two drops of damping fluid and that seemed to help quite a bit. I must also mention that VPI's customer service is great. They listened to my issues and were not familiar with my cartridge, so they did some research on my cartridge and called me back with some solutions to fix my problem. So far I am very happy with my treatment from VPI.

Anyways, the new table sounds great. It is a huge step up from my Rega! I loved my Rega and it sounded really good, but I didn't know until recently what I was missing. The VPI Classic has really transformed my system. The soundstage is much wider and deeper. Recordings that sounded flat on my Rega sound fantastic on the Classic. I also noticed a giant reduction in surface noise. So, overall I am very happy with my purchase.
The the rear of the tonearm was wobbling like a bell. The damping fluid seems to have help with that. It will wobble for about 10-20 seconds and then it settles down with very little movement. I am using a salamander rack at the moment, but I think I might try to squeeze my Levinson 331 amplifier on the bottom of the rack for more stability. The rack is rather tall with my table on the top which is quite heavy. Maybe that will help further stabilize my table. All of the heavy components are near the top of the rack.
