I recently came into a NOS MMC20 CL-C. The final "-C" apparently specifies that this cartridge has a rare stylus called the "Win super-ellipsoid" stylus.

I'm eager to find a time when I can properly set it up and give it a listen along side my MMC20 CL and other "20" series cartridges.

Anyone know anything about this cartridge and stylus?

 Thanks in advance for any insight you can offer.
 

I have two of these that my parents received as gifts when they toured the factory in 1980 - didn't realize they had the -C designation till I checked after seeing your post. I know nothing about this model but would love to hear any info you can find.

Thanks,

I know we have spoken about this before - and your stylus may be a special one - but the MMC20CL-C is normally just the version ith the Universal Connector. There is also a 1/2" model.
