I'll agree with tablejockey. You are much better off with a reflex clamp. The best one is made by Sota. You should not have to use a clamp with this vacuum contraption as it does have a seal around the label.
Audio Technica AT 666 vacuum disc
Is anyone currently using it?
I have it on trial, the product is almost perfect NOS, but after about 7-8 minutes the LP loses its vacuum; is it necessary to also use a clamp to get the vacuum for the whole LP?
