Ouch.
I really feel for you. I know what you're going thru and it sucks. That older gear sounds fantastic and you want to play it forever, but you just cant.
I went thru the same thing but with an old Memorymoog converted to a plus, except my problem was that I had to hit the autotune button 3-4 times a SET. It had me stymied. I couldnt find anyone in the US who even wanted to touch it, Big Briar had folded and the only guy that was doing any work was half of Big Briar - located in Germany - and at the time he wanted $5k to work on it, modify it from a Plus back to a standard Memorymoog and shipping to and from Germany (yeah. right. Ship a Memorymoog in any case - I did have a flite case tho - to Germany and back). I got lucky and got $500 for it for the parts....

Good luck with your OB-Xa.
