If the stylus is unharmed I see no reason for tossing a part that can cost you several hundred dollars. (A quick google shows that refurbished cartridges are sold from $100 to $500 on the net.)

As far as I can see the black part only protects the needle and yes, superglue should work fine. I'd probably use some adhesive tape first to keep that black part in place. Plug the cartridge in and see if it works as expected.

Hope this helps!

thanks for re-posting my photo...

If the black plastic part is broken off, then whatever caused it to break could have hit the stylus as well... However, it serves no functional purpose with respect to the audio signal.

Note, however, that the plastic does have mass (as does CA glue that might be used to repair it) so you might want to consider checking the tracking force; just in case...

Thanks for your advice, guys. Don't know when I'll get to doing this (still working on my Beomaster 6000 4-ch.  - which continues to be a major project). And thanks for the reminder as to checking the mass; easy enough to do that.
