The Michell clamp simply works the other way, creating a slight convex surface. Both are good for reducing the effects of warps.

Sorry, the MAT, not the platter
I can't go on and I can't go back, I don't feel so matter of fact,
I tried and tried to make good sense, What's the good to try it all again?
Ah, ok. Was the idea that the record sagged a bit under its own weight, to fit the concave surface?

I don't think that's quite the case, Dave. No-one gets "hounded away" from here unless we sense they have an agenda. And the only time the chap you're referring to contributed to discussions was to pooh-pooh (perfectly well thought-out and designed) aftermarket modifications for the SL-1200.I remember the ex-technics engineer who posted here (before being all but hounded away)...
It's almost as if he took it all personally... And when I challenged him on that, he went into a huff and left. There was definitely something strange about his presence here. Anyway, we move onwards and upwards!

Hi DaveSorry, the MAT, not the platter
If the information i have is correct , the OEM rubber mat is designed to sit on the lip and you are supposed to use a weight with it (not a clamp) for best results !
Interesting that Dave Cawley has been saying for some time its a design fault ? I don't think so , I've not used the rubber mat for over 2 years now , so now i have this alchemist weight , its time for a revisit i think , probably hate it but WTF.

The "lip" is a tiny fraction of a mm on the SL1500, so the mat would barely register it I think. The mat moulding does seem to have a small dip towards the centre though.
I can't go on and I can't go back, I don't feel so matter of fact,

Received the Achromat today. Compared it to the Origin Live mat. Prefer the latter; the Achromat sounded congested in comparison. Prefer the the more open sounding OL mat.

If you are using the standard platter can you use the OL mat direct or do they recommend using with a rubber mat underneath?

I am using it on the MN platter now.
I used the OL mat directly on the stock platter before; it did not work for me. I actually had good results using the OL mat on top of the Oyaide mat. Did not try it on the rubber mat though.

Hi guys
Been busy, are we on about TT mats again? You simply must try the blue horizon mat chaps, highly recommended.
