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.

Very confusing. You sure you don't have the platter upside down? :^)

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???

Yeah, I understood, I was not serious there either prince, the platter is properly installed :-)

BRF: I am not talking about the washer. From the center spindle is about 5 cm radius (label) which is raised about 1 mm above the rest of the outer platter. With the washer, the center (label) is raised about 3mm above the outer outer platter. I felt pretty confident after talking with Jack at VPI that this is correct, but now, I've got no idea.

Guess I will have to put on a new copy of Miles and Monk at Newport (mono!), open a cold beer, and think about this one some more.
