Heavy clamps increase the wear on the bearing.
There is no reason for them to be heavy if they have correct mechanical design. Screwing onto a threaded centre pin is a much better approach than using mass to hold the record down.
@simao It's really quite difficult to get a TT to run at 33.333333 rpm.
And a cogging computer controlled direct drive is not the way to do it.
@chakster 3kg??? Many TTs have platters weighing 25kg, some much more.
Over-engineered glitzy TTs with extra bling are one of my pet hates.
