VPI Classic platter - is center milled?


Is the vpi classic platter milled with a depression in the center? vpi recommends not using a mat, but my platter has a slight rise in the center.

With the provided ring clamp and gasket, vinyl stays 2 mm above platter with a lot of wobble. If I use the rubber mat, it seats the vinyl firmly.

Thanks for input.

Reprince, Not really if it's upside down or not. I will call the factory and get back to you.
I was half-joking, but given the confusion I figured I'd ask. I know Jack, and I'm sure that he would know his product, so the conflicting answers indicate some confusion in the communications. Simple way for you to check would be to lift up the platter and check the other side, I guess.
Abp689, are sure you are not talking about the centre being raised when "using" the supplied rubber washer which is meant to be used with a reflex clamp???
