Technics SL1200 Footer thread size?

Tvad,

M6 = 6mm diameter, yes, and for a bolt you also have to specify the length, usually in centimeters. More info here:

I use the PartsExpress cones too. Supplied threads happen to be an exact match for the SL12x0 series. Very noticeable improvement when I replaced the stock feet with these cones and then set the TT on a thick butcher block cutting board.

At about the same price as the Mapleshade brass heavyfeet, http://www.kabusa.com offers the Isonoe Footers, which are also supplied with M6 threads and designed to be a premium replacement for the standard feet.

The reason I asked about M6 vs. 6mm is that sometimes the distance between threads is different even though the diameter of a bolt is 6mm.

Not sure if I'm going to replace the Technics' feet, but I was considering brass footers from Starsound Technologies (Audiopoints), or the Isonoe feet.

I recently installed a sandbox under the Technics (designed by Thom Mackris of Galibier Design, and built by Timbernation), that has made an improvement over the Neuance platform I was using previously. The image is larger and clearer, and my perception is that the volume level is higher at the same setting on my preamp. That's probably not true though.

Anyway, the rig sounds great as it is, and I have no huge desire to change the feet, but I was curious about what adding brass feet might do.

Yes, that's called the pitch, In USA thread specs, it can be referred to as fine pitch, medium pitch (I think), and coarse pitch. I'm no expert, (though I've done some basic work on metric-spec autos), but I've never come across a similar pitch descriptor for metric threads--at least of what shows up in the US.

From experience, I can tell you that the thread diameter and pitch of the female threads in the base of the Technics TTs, the male threads of the stock feet and the Parts Express cones are all a perfect match, and I've read enough testimonials here to safely say that the thread and pitch of the Mapleshades and Isonoes are a match as well.

It also appears that one of the cone sets at http://www.adonacorporation.com/tweaks.html is the same as the PartsExpress ones, and are about the same price.
