Record weight / clamp for Thorens MK II

Hey, all,

I have a long-in-the-tooth Thorens TD 125 MKII turntable, and a bunch of old records that need a record weight/clamp.

I use a KAB Speed Strobe for accurate speed checking with stylus drag and weight, so the clamp needs to come on and off easily without affecting the delicate speed settings any more than necessary.

Any suggestions for this vinyl to digital archiver?

I'd really like to get this one, but I can't find it anywhere, so far:

It would let me check the speed with the weight on.

Thanks,
