Is that the correct model? On my EVO, there is a switch under the plinth on the left side for 33 and 45. I only have to move the belt for 78s. So, basically, never.

Did it come with the Sumiko instead of the Ortofon? While the platter has dampening material around the inner edge, it does still ring a little. I opted to upgrade to the acrylic platter a few months later. Makes it look fancier too.
