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?

Jonathan, Thanks for that information.  If COVID ever permits me to visit Tokyo again, I will look for one of those two accessory mats.  Are they readily available in Akihabara, like at Yodibashi Camera?

Also, I want the P3 shown in the teq advert.
best-groove round elastic for men’s socks, what is that and where did you find it?

I apologize, I have only read in this moment.
I have owned it for a long time but you can find it in any resale of sewing threads and buttons, just ask.
This thread is very elastic about 5 or 6 tenths of a millimeter.

@lewm that of the link is not the P3 but the PL 70II.

The P3 is the one I have in the photo in the avatar. :)
Dear @best-groove : Totally rigth in the Pioneer  issue, here the P3:

In the other side about something that you have to take with any vacuum LP hold down  is to mantain the platter clean to avoid that minuscle " dust " stay clamped for ever in the LP grooves at the same time that the LP side face-down to the platter be cleaned to protect it and to protect the rubber perimeter.

raul, didn't you comment a few years ago that you found the AT-666 improved your SP-10 Mk2, even without using the vacuum feature?  Possibly better inertia from the (then) heavier platter?
