Dual 721 platter

[Anthony R]

I won a Dual 721 turntable off EBay the other day, and I think I got a good price for the winning bid of $367.

I have other Dual turntables but never a 7 series. Can someone explain the platter and it being a two piece platter? I’m a little confused about how it works and how to place it back on the turntable.

It will be here on Friday and I want to set it up before I send it in for servicing.

It is not 2-piece, it is one platter and it stands on top of the motor. What you see once you remove the platter is the motor.

Yes - think of the top of the motor as the inner platter with the "platter" being the upper or main platter. It is also the flywheel of the direct drive motor and is crucial for proper operation. Don't run the table without the upper platter in place.

Are you thinking of the mat?

The photo on the left is the inside of the upper platter - the center photo is the inner platter/motor top - and the right side photo is the platter right side up on top of the inner platter/motor with the mat on top.

Hopefully this is descriptive enough! The 721 has two revision or designs to accommodate more strobe marks. This is most evident based on the design of the platter mat.

Here is a photo of a 721 I used to have with the first generation platter/platter mat. You have the second generation platter/platter mat.
