Send it to Soundsmith as I did. The first time, they were able to re-attach one of those hair-like wires that protruded from the side of the cartridge that I tried (don't do this, in other words) to tuck back in the grooves on the sides and broke. It appeared they used some solder and joined the wires back together. This may be all that is necessary with yours and if I remember, they charged me about $80 to do the repair.
Had the cart for a couple more years before the left channel went out.....sent it back to Soundsmith and this time they said it was dead and not repairable. No charge for the evaluation, but I think that is because they had worked on it before. You might be charged the evaluation fee ($75 if I remember correctly). They are a company that deserves the high regard attributed to them (no affiliation by the way, just a pleased customer who has had several rebuilds done by them). If you like your Blackbird, this is how I would suggest you proceed. For me, I am going to think twice before considering a cartridge that is as vulnerable as this one as even the slightest touching of the sides can be disastrous. I'm pretty careful (although admitting the stupidity of my first try to "retuck" those wires) but when it comes to setting it up, man, it's a constant state of angst to avoid the sides of it and just grasp it where it is safe, and that is not an easy thing.
