I owned one about 25 years ago. If my fading memory serves me right, the mass was mostly in the nut that screwed onto the arm post under the plinth. At the time suspended belt drive tables were all the rage and the mass of the Lustre nut was too much for the likes of Linn and Oracle among others. I believe it had a magnetic anti-skate and I know it had VTA adjust on the fly. It would probably be great with these Lenco set ups that are now popular or anything else with a heavy plinth and no springs.
