SpEClAL NOTE: The Dynetic stylus assembly used in these car­tridges is the most critical component. To maintain the original
performance standards of your cartridge, be certain that any
placement stylus you buy bears the tollowing certification on the
package: “This Dynetic stylus is precision manufactured by Shure
