That first version of the YBA200 has an auto-biasing feature which failed on a small number of those amps causing Traynor to switch to a fixed biasing scheme that requires the services of a qualified amp tech (hence the YBA200-2). Years ago Traynor offered a free upgrade to convert YBA200s to the YBA200-2 spec.
This doesn't mean the particular YBA200 you are pondering is a bad amp (about 6 months ago a TB'er in New Zealand, IIRC, bought a YBA200, and after a round of e-mails with the folks at Traynor it was decided that the upgrade wouldn't be needed on his amp--which he went on to enjoy immensely).
If the YBA200 you're looking at still runs well after all these years then it will likely continue to do so.
But as a contingency you may wish to e-mail Traynor for availability and price on said upgrade, and for some advice on how to care for the amp.

BTW. The
YBA200-2 product page has links to the owners and service manuals which I believe covers both versions of the amp.
EDIT: I was mistaken ^.
Here's the owners and service manuals links for the YBA200.
