Yes, Ortofon will rebuild the cartridge.

I see now that it is Ortofon, now that it is too late to change it. How embarrassing.
What I am not sure of is which level rebuild to go for, ruby cantilever or aluminum, which profile diamond, that sort of thing.
Also I see now that it is the elliptical version.
Should I go for stock or an upgrade ?
Viridian, thank you for your interest.
I must tell you that I was surprised that this very early cartridge is still considered a high end contender, just because of its age, not from any personal experience.
I want to use it at its potential, not particularly interested in historical accuracy, but don't want to destroy a classic either.
I listen almost exclusively to classical, only occasionally to Rock or Jazz. Not all my records are in perfect condition.
I currently use Shure M97xe, Denon 103R. Technics 1200 TT.
As my record collection has grown, I have been considering a serious up grade in vinyl playback, but this cartridge just fell into my lap.
It is not usable in its current state, so I am all ears.
If you use a Technics 1200 stock arm, it would not be able to balance the heavy 30+ gram mass of SPU-GT on the end of it nor would it be a good match even if use a heavy custom counter weight IMO. If you do upgrade your vinyl setup and plans to use the SPU, Schick, Ortofon 309 and Fidelity Research FR-64S are all good arms for SPU.
As for rebuild, Expert Stylus & Co in UK can rebuild SPU but there is a long wait.
I see what you mean Jaspert, the Technics with the supplied aux. weight can balance up to a 13gm cartridge, and the head shell is 6gm, for a max. of 19gr vs the 32 for the SPU.
I will rephrase my question :
The various Sound Smith re-tips run $150, $350 & $450, for example.
Assuming a suitable tonearm, does it make sense to spend that much on a repair, or spend the money on a new cartridge ?
Thanks Viridian, do you have an opinion on what level of repair would bring out the best in the SPU ?
At Sound smith it seems like the choices are: aluminum cantilever, ruby cantilever and ruby cantilever with special diamond tip.
Jaspert, How does one get in touch with Expert Stylus & Co in UK ? The don't seem to have a web address or even e-mail. I could send an Owl, if I had one, I suppose.
I like the look of the Schick arm, haven't seen anything so minimal since the original AR.
What about the SME arms ?
I confess I am a bit at sea here, but this was not a planed acquisition. I bought out a estate's record collection, and at the very end, they told me to just take anything or every thing.
V, making a counter weight is not a problem, I have my own lathe.
The reason that they make three different levels of cantilever/stylii at Soundsmith is that different people want different things. I would get the elliptical/aluminum, because first it is closest to the original setup and second, a little less detail can be a good thing with less than pristine records. But my needs are, no doubt, different than yours.
I would have a look at the level 2 as well. Sometimes the more radical stylus cuts will ride at a place in the groove, that has less damage, and can actually sound more quiet.
How about this answer, since you are dealing with a bespoke repair, why not consult with Peter Ledermann, since he will be doing the work, and take his guidance on the most appropriate rebuild for your needs?
BTW, why can't I find these estate sales with SPU cartridges and piles of Western Electric tube gear?
