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.

......,Changing to a flat record may be (sorry i m joking)
This should not happen , you have the 10,5 or the 9 inch arm i suppose, as it is a unipivot i dont see the problem , the arm maybe to high on the back but youve tried that already.
Is the table positioned stable and flat (measuretool) and are the srews of the arm tightened, i would try another cartridge then and see what happens .
Do you have the table standing on a wobbly floor?

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.

Isn't there a slight problem with VPI arms that don't seat firmly onto the point of the unipivot bearing? (I've seen that before.) It's easy to lift the arm off of pivot and try to make sure it settles back onto the pivot correctly and firmly.

Someone asked about a TTWeights ring with the Classic. I have the 600g ring but find that it imparts an unpleasant metallic brightness to some material (is this what people call ringing? no pun intended) and now generally avoid using it. This is a shame since I very much liked what the ring did with my previous table. Maybe the copper ring is not a good match with the aluminium platter? I've sometimes wondered whether the much heavier (but, unfortunately, also much more expensive) VPI ring would avoid the same problem. Can anybody speak to this?

I was the person who asked about TTW and the Classic and have since purchased the 600g ring. I don't think I'm experiencing what you described; granted, I wasn't blown away as some said I would after using it, including the manual, but certainly now enjoy some of my warped records thanks to the ring, when I would simply not play them at all before.

I also wonder about the "ringing." The ring does not touch the platter; it simply flattens the record. Why and how could it impart any significant aural characteristic on the sound? Is there any science behind this theory, or is it simply nonsense?

Lastly, I don't care who machines the VPI ring and how sophisticated the process is; the price is beyond absurd for an accessory.
