There was also a 660,

There was also a 660, virtually identical, which came out in the mid 70s.
sadly most the ones I've seen in the last few years have been defectiv, the rubber suspension deteriorates. I don't think you can open them up without destroying them, they are glued tightly shut!

Dual 650

Hi, does anyone know if it is possible to order a replacement pick-up for the Dual 650 type? Thanks, Geir Walter

Dual ceramic cartridge.

Leave it to Dual to be serious about a ceramic! They even have a frequency response graph inside the manual. I am impressed. And it is a handsome cartridge too.

Simple modifications and a modern stylus /compliance will turn it into a decent electro static cartridge.

not MM but crystal

Please note, that the CDS 650 is a crystal system (as we call it in german), not a moving magnet system as shown above.

not elliptical stylus

DN6 is two stylus spherical!!
