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?

Dear @best-groove : You can use that nylon line for fishing rod or aguitar chord and it has to hold around the rubber with some kind of thigthness. What is difficult is to make the knot in the nylon new thread for it be/stay tight against the rubber but not so tight that the nylon that tear/rip the rubber. if it’s a little loose then the vacuum hold down the LP for short time only. So not an easy task.

You need to check too that the 666 valve is running ok with no loose and that stay at the rigth position when closed to mantain the vacuum hold down.

@rauliruegas very well, only the original nylon thread was missing, I solved it with a round elastic for men’s socks; now the vacuum holds exceptionally for over 25 minutes.
I am very happy, I really think I’ll buy it.
@best-groove round elastic for men's socks, what is that and where did you find it?

Also, for future reference, I remember reading that air leaks can happen with the valve.  If you're not able to correct that then a good bike repair shop may help.
There are methods that are reported to a effective repair to the leaks that can occur to be found with a Web Search.

The AT 666 has become available within my Local HiFi Group and the use of one will eventually end up being compared to a variety of Platter Mat materials and LP Clamping methods in a few different systems.

If all goes well it might show it can do what a Periphery Ring and Puck Weight can achieve.

Is it offering more than a Ring and Puck can offer.
