Hello everyone. My puck ring for my MD2 got sticky so I decided to replace it. I ordered one from Krell & they sent me one that was much thicker than original. I put it on anyway & now the puck wobbles. I have a feeling its due to the wrong thickness in their rubber. Krell claims this one is right but I know for a fact they sent me one for a CD DSP because I have one of those & the puck is designed different than a MD2. If anyone has a MD 2 would you please measure the thickness of the rubber with a micrometer? I can get one custom made with a laser engraver if I knew thickness. thanks
