What do I do with these Cartridges


Hello all,
I've got a couple old Cartridges, a Sumo II MC and a Dynavector Ruby. On both, one of my wonderful children broke the cantelievers some years ago. Today, I listen to mostly computer audio and I have replaced these with an Audio Technica AT440MLA. It is fine for me these days.
Are these worth having repaired? Better to sell them as is? Not worth someone else to buy as is? or a No brainer, YES, get these repaired.
I haven't followed cartridges closely over the years, so I'm fairly clueless of their value. Thanks for your help, Tim

I do not know the Sumo... but the Dynavector ruby is a definite YES.

The current equivalent is the Dynavector Karat 17D3 (you can look that one up).

Soundsmith have been known to recantilever/repair these.

Alternatively you could sell it... but for the $300 odd that a retip would cost you, you would have a truly exceptional cartridge (Retail is currently well over $1000 I believe) - Of course I am assuming that you still have an MC phono stage to run it into.

bye for now

The Ruby does not sound anything like a 17D. It didn't when they were both brought out(23R-$310.00/17D-$650.00), and the Diamond has been improved, more yet, as of late(17D3 version). Damaged Karat Rubies bring about $50.00(average) on eBay. The Ruby was a good cartridge. The Diamond was/is a great one.
Thanks so much, all good info. I'm thinking I might start with the Sumo and tackle putting a new cantilever on it myself...
@Timlub- Here's something that you may find of interest: ( http://www.vinylengine.com/turntable_forum/viewtopic.php?t=22847 ) Personally; I would find something more rigid than a cactus needle, though weight is certainly a major factor.
Thanks Rodman, you might remember Marcof Electronics, years ago I was general manager there, we made moving coil head amps, speakers, cables & modded phono cartridges as well as amps & preamps.
I have laid my hands on (modded) a few cartridges over time. I think I can do this competently. I've read the vinylengine article before, If I recall, they did one of the Sumo cartidges there. I truly appreciate the responses. Tim
