Dynavector 17D3 hitting clamp on VPI Scout

Hi, everyone. I've got a serious problem with my new Dynavector Karat 17D3. It was professionally installed and set up on my first-generation VPI Scout table with the JMW tonearm. It works fine until the stylus goes into the blank grooves at the center of the record. Then the side of the cartridge hits the VPI record clamp. Aside from the loud crashing sound this produces, the dealer says that the impact may damage the stylus. For the moment, I'm playing records without the clamp. That's not really a good solution, though, since the clamp performs an important function and is recommended by VPI. Have any of you encountered this problem? Any tips for a solution?

Geoff, I have made that assumption. As long as the bearing stays lubricated, I believe it to be plenty stout enough to handle the extra weight. Between the copper mat and the brass clamp, it's probably close to an extra five pounds it is supporting. All I know is the sound from the Scout is astounding to me now, I feel I have finally fulfilled the promise that vinyl offered, but eluded me for years, until I figured out how to unlock the secrets to fulfill that promise. Whew! At last!

Best of luk,
Dan

Years ago I used a Clearaudio Gamma, a very wide cartridge that did the same thing on my HW19III--I special-ordered a one-piece clamp from VPI- it looked like they ground the outside of the tapered perimeter of the clamp-problem solved. There is still about 1/8" of material around the perimeter that actually presses down on the record. I've used this clamp for 8-9 years now with no problems; of course I'm using a different cartridge now.

I do think the machine shop might be the answer, or you might call VPI for their recommendation

Problem solved. I upgraded the 17D3 to a DV XX2 which has a narrower body.

Hi Madcity i have the same problem as you, so instead of changing or up grade to a Furutech Monza which is 3" dia vwhich work fine vs new dyna xx2,
i think your choice is much better. i have tested the Furutech monza very little improvement
i have 60 hrs on my 17D3, may i ask how much improvement you get, and what is the different price you pay.
thanks

I've heard of this problem a few times. If you send your clamp back to VPI, they will take a sliver off of the periphery. Problem solved
