This is an original NOS Dual cartridge in bulk box. The cartridge is mounted with a DN-8 double sided sapphire stereo stylus.
Dual CDS-660 was originally build into the tonearms of Dual 421, 427 and 430 turntables and was attached to the headshell with the HS-421/430 clip (part number 223 551).
The Dual CDS-660 can be used as a replacement for the no longer available CDS-650.
