Audio Technica AT 666 vacuum disc

I was once hunting for P3 but decided I’ve got enough tts.

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.

I have a question about the AT666 which occurs to me probably because I have never seen one in the flesh:  I can understand how the mat holds the LP, but what holds the mat to the platter?  Does it generate vacuum suction on both sides?

Thanks, Raul. I knew you had experience with those things.

I think they were pretty good when on the market. But now they’re old and prone to lose vacuum due to air leaks in the system. Given your observations I’d worry about that. If you could localize the leak, you may be able to effect a repair.
