Astatic N8, 700d7; diamond replacement needle for 33/45rpm records. For Saphire 78rpm select w/78 option (diamond is not available). We also have a 3-pack of saphire needles for $10.00, select the -2.00 option to select 3-pack. Saphire needles do not sound as warm as the diamond counterpart and do not last as long as a diamond would. The upside is that the saphire tip is softer so less damage may occur to the vinyl depending on the weight of the tonearm. The needle is held in place on the cartridge with a small screw. Many cartridges had 2 needles, one on each side, one for 33/45rpm and one for 78rpm. If you would like one of each, please select that option. Note: If you want to mix options (buy 1 or more of one type and 1 or more of another), make your inital selection and add to your cart, then return to the item, make your selection and add that item your cart. This needle was used in many portable record players and older cartridges:BSR TCH, etc, Panasonic EPS04LP; Ronet DI075, SA075; Varco/Vaco TO-l,NBS12,14DLP;
