Triples were terrible devices. OK for touring bikes but absolute trash for racing. They were usually a 52/48/30 though a lot of people replaced the 48 with a 45 or even a 42 on the later 130 mm triples. They were forever misshifting in a racing setting and that was the end of your race at that point. Plus I was a lugger so there was no reason for me to have a 30 tooth.

Campy 10 speed doubles would only shift a 28 though if you used a Daytona rear derailleur you could shift a 30 tooth cog.

The long cage models are called 'triple' by Campagnolo
because they do not produce an 'offroad' series. The long
cage model is what you want.

Those long arm Record rear derailleurs were really hard to come by. I think I got one off of Ebay because Robinson's tried to order a new one and it was not in stock and they were talking about months to get it. I finally got it and it's around here somewhere since I didn't throw anything out.
What broke was called a "reel". I tried the end of the shift cables into it and they fit fine but the one that jammed was out of round and more oval shaped. Or I suppose that is why it jammed since out of a package of 10 I found three like that. It pulled in from the spring tension of the rear derailleur and then split the reel. While the 11 speed reel is metal, the 12 speed is a plastic casting. The metal reel and the plastic one couldn't have any weight advantage since they are both less than a gram.
I seem to remember we had an argument about that and you insisted that I should be using Campy shift cables. I ordered a package of them and maybe they were counterfeits since they didn't have the "c" stamped into them but were part of the casting and stuck out from the side of the ends But the Chinese versions were fine as long as you didn't use one of them that was oblong rather than round.
Right. Campagnolo Record Ten was displaced by the eleven speed system in 2009. Less expensive models (Chorus, Centaur, Veloce, Mirage) in long cage are compatible with your Record 10 Ergo levers.
As we discussed earlier, you are having problems because you are using 4.5mm gear wire heads in your system designed for 4.0mm gear wire heads.
history note: gear wires were 4mm all brands (Simplex, Campagnolo, Zeus, Favorit, Cyclo, etc) until Shimano and Suntour adopted the larger 4.5mm format. The trouble you're experiencing is not a wire manufacturing error. It's the wrong part. Same trouble would ensue in a Simplex shift lever.
tech note: Campagnolo wires measure 4.0mm diameter AND have a 'C' cast in the head.
