Hey Tvad, are you the one who got an AT150MLX cartridge and got rid of it because it revealed too much surface noise (or was that Viridian)?
I did a little platforming tweak to my SL1210 that dropped the surface noise like a stone.
Basically, put threaded cones on the SL12x0, get some floorsavers at least 1-5/8" in diameter, and place these on a set of #2 Vibrapods. Situate the cone points on the floorsavers on the Vibrapods. Place that on a platform (I use a butcher block cutting board) and pad the cutting board with a couple of 19" gel wristpads made for computer keyboards. Or you could use another set of Vibrapods under the cutting board.
