[QUOTE="GECO, post: 75669, member: 415"] the problem with the bearing sub platter is the following. you got a metal ball making contact with a semi polished metal shaft. this shaft/platter is mounted directly to the glass platter, so you can follow the noise transfer to the cartridge. rapping it in PTFE tape only hides the problem good aftermarket mods Ruby ball zirconia ball on ruby contact surface isolated platter from sub platter etc etc etc [/QUOTE]
