Turntable Weight from Varia Instruments.

The 7“ adapter inside the weight is moveable- as soon as you put the weight on a 7", the adapter will fall down through the big hole of the vinyl. Your record is now centered and stabilized by the TTW10. If you place the kit on a 12“ record, the adapter will remain in the rear position and stabilizes your warped records. A sticky rubber mat on the bottom side protects your vinyl and allows you to control the record in a very direct way. The weight comes in a printed box with a linen bag for secure transportation.
