The platform is comprised of three metal boxes, each with an aluminum half sphere 'piston' on top. A granite slab is placed on top of the 'pistons'. When the whole load is pushed down the 'pistons' act as springs ( and also work in the lateral plane ). The frequency of up and down cycles is dialed in to about three to five per second and the turntable leveled. It works like industrial platforms where the resonant frequencies are shifted down, but with pumped air instead of metal springs. It's really good, especially because the 1200's problem is handling lateral vibrations--not vertical.
This device and sticking Marigo Dots on the gimbal bearing housings & cartridge has brought a new dimension in clarity and definition. Keeping the bearing oil all the way to the top brings big improvements, too.
