What Record Clamp for LP12?

J.A. Michell clamp was the lightest I identified. One problem is that you will likely need to stop your table each time you change LP sides--unless you don't mind adding ALOT of rotational torgue at each record flip. I finally decided not to buy/use a clamp. LP12 was not aurally designed for one, can damage bearings and suspension. For me, it was a momentary (month-long) obsession. If you decide to try it, I hope you'll report your results. Good luck!

At the advice from all who seem to have an LP12 I have decided to forgo any clamp. Thanks for all the input.

If you thing to need one, than take a light clamp, but never choose a Tonar I think its the worst thing ever designed!

I owned a table similar to the LP12, a Logic DM-101.  The problem with using a record clamp "sometimes" is that the table is balanced either with or without the clamp.  If you balance it with the clamp, the suspension will be off without it, and vice-versa.  The center of the platter isn't the center of mass of the suspended subchassis.

 

I think record clamps are a 'no no' with the LP12, for all of the reasons mentioned so far. IMO, if you need a record clamp, there is a big possibility that your record is warped, if that is the case, you are simply adding a band-aid to the problem, better solution is to try and source non-warped records. ( not that easy, but--)
