If that's the sort of triangular aluminium plate thing, then I still have one somewhere. Not sure how to get it to work with my Decca though!But the guy who built the custom DC supply for my Source as well as rewiring the Zeta (Steve McCormack at the Mod Squad in California) recommended I try his 'Cartridge Tip Toes'....basically a thin plate (I cannot remember if it was plastic or metal) with three small bumps that interfaced between the cartridge and the headshell. It only cost like $15 or so back in 1985, so I gave it a try.
Yes...it was triangular. I think the bumpy bits face upwards to contact with the headshell surface and the flat side faces the upper body of the cartridge.If that's the sort of triangular aluminium plate thing, then I still have one somewhere. Not sure how to get it to work with my Decca though!
