I have an FR 3080 four channel turntable and am trying to put it back in working order. It seems to be missing the anti-skating wt and stylus. I can purchase both on ebay with a little searching, but need to know the weight of the wt and the lenth of the nylon string. There is an SC-50 Sansui cartridge on the arm . What quad stylus do i need for this cartridge? I would appreciate any positive info on these questions. Also , would a service manual have info on what equipt /parts came with this turntable? Thanks again , and great site. Bob Macias
