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.

I mentioned his communication to you BRF. At first he said it was recessed, I said mine was raised 2 mm in center. He then said, correct. It is raised.?.

Second stringreen to decide the win here. It's getting exciting.
Summary:

The OP has a platter with a raised center.
Jack Rubison at VPI says it doesn't, then he tells someone else it does, then he tells Brf it doesn't.

Are things OK with VPI these days?
Reprince, Not really if it's upside down or not. I will call the factory and get back to you.
