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?

I was just kidding with you.

The 12 inch 45 RPM records are usually about 7-8 minutes per side.
I just watched a video on this contraption. How was this ever thought to be a win?

Looks like something to toss in your audio junk drawer after the novelty wears off. Why not just get one of those reflex clamps with rubber spindle washer?


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.
@lewm   I am interested in knowing from who is currently using it how long the vacuum lasts, I have to monitor the situation.
The rubber is very soft, without cracks or cuts, as soon as the vacuum is done I can lift the LP and the metal plate without problems.
