I have converted an eight speed record ergo shifter to nine, using a disc for the 2001 levers. It works flawlessly as a nine speed lever, all I have changed is the indexing disc.
I have a Chorus ten speed lever, and was thinking about putting the nine speed disc in that lever. I read on the Branford bike site that I would also need to change the racheting disc, which I did not have to do for my other conversion. Is this really necessary? The rachet disc just rachets, not indexes, so I would think that any rachet movement would be the same.

No it's not necessary...why branford says this along with some of the other stuff tells me they don't try it before they spout the 'company line'.

If you have a 10sp ratchet, you don't need the ratchet disk. If you have a 9sp ratchet disk and go to 10sp, without the 10 sp ratchet, the throw of the lever between shifts gets out of sync but works fine. I haven't replaced a ratchet yet and didn't know anything about it until 10 days or so ago.
If you didn't know, you'd be hard pressed to find the difference.

I'm sure this has been covered berfore but... is it possible to convert '98 Record ergo to 10 speed? I think mine are '98 or perhaps '97 or even '96. I converted them from 8 speed to 9 speed years ago. Can I go to 10?

If they were 8-speed to start with, they're '96 or earlier. '97 levers were 9-speed with the old hood shape. '98 Record had the new shape hood with aluminium levers. 1999 saw carbon levers.
You can convert the lever to 10-speed, but not by simply replacing the ratchet. You need to replace most of the innards. Unless you have a very strong preference for the old hood shape, it's probably not worth the cost.

Do you mean the EC-RE133?

Why do the 2001 9 and 10-speed Chorus right hand Ergos have different ratcheting discs? If they don't do anything different, why does Campagnolo bother?

Ratchet movement might be the same but what about amount of lever movement required to get that? Wouldn't the proper disc reduce the amount you'd have to push the lever to get a click, or is it the other way round?
I really don't believe Campag have two versions for no reason as they like to share parts whenever possible.

8-speed and 2001 9-speed cable ratio is different, whereas it's the same for 2001 9-speed and 10-speed.
Pete I am not sure if the part i have is the ec part number you mention.
I do have a question, tho, if the cable actuation for 01 nine and ten speed is the same, could you just use a ten speed lever with a nine speed cassette, and just adjust out the bottom or top index position? Mark

If old shape or 1998 (first year of new shape), it is possible to convert to 10sd but you need almost the entire innards, front to back. In 1999, they went to Ergobrain innards, that changed the way the whole thing is held together, then to 10s in 2000.

Part numbers can be found on the Spare Parts section of Campagnolo.com.

No because 10sp lever pulls less cable per index click than 01 9sp lever. It's just that the 10sp derailleur travels by the same amount per mm of cable pulled as the 01 9sp derailleur (in fact the new 9 and 10sp derailleurs are virtually the same things). That's not the case with 01 9sp and 8sp.
I thought that might be relevant somehow to explaining why a different modfification is required for 8-to-9 than 10-to- new9. I must admit that I can't quite get my head round all the math.... just throwing some ideas and facts into the mix in case it helps you and others to figure it out.
