I have a VPI "Classic" and experienced the same problem as the OP. I have a TTW lightweight stainless center weight, a TTW copper peripheral ring, and I have an Ortofon A90 cartridge mounted. I also have a Boston Audio Design mat. In my case it was the headshell that ended up hitting the center weight not the cartridge, but the result was the same; probably the worse noise I have ever heard come from a turntable. As it turns out, I decided I prefer the sound of the table without the center weight, but absolutely, no question, prefer the set up with the periphery ring.
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?
