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.

The tonearm should be rock solid. Something is forcing it to wobble. Make sure that the belt is not twisted or nicked. Also put your hand on the table while it is turning and feel for any vibration such as an out-of-roundness in the platter, or the motor shaft. Don't worry, Harry will make it right.

also...VPI tables have 4 feet. When leveling the platter, check to see if the weight of the table is spread over the 4 feet. Its very easy to level the platter only to find one of the feet not even touching the table on which the turntable is resting.

There is a difference between VPI's Super platter and the aluminum one that has now become the reference...it is used on the rim drive Superscout. The difference is mainly that the aluminum platter is less weighty and focuses more on the upper frequencies. I don't get the feeling that it RINGS....there is no overhang or sustaining of those highs that I can hear. Aluminum is much easier to get perfectly round so that its timing is a we bit better than the Superplatter. Used with the VPI clamp and ring, they both are excellent....just a bit different.
