Xpantastic!

Hi there, just the one DAC in the Xpander- i dont think you have to have one 
for spares, but they seem to be a hard to find part, so if you want to get 
one as a precaution then it might be a good idea, i grabbed a couple when a 
saw a few nos going fairly cheap a few years back.
Yes- the vfd screens are great on the replacement display board, my unit was 
the test machine for that, i have the first unit installed in mine and its 
great, not had any problems at all, my old screens were dim and failing 
otherwise i wouldnt have bothered either- but they are great and i think its 
good value for money, steve (@ benden sound) has been repairing and 
modifying my gear (when he has the spare time- not his main line of work) 
for about 5 years or so- hes a really good guy.
Regarding the cems, i cant see any more being made unfortunately, its 
definately a good idea to have a few for spares, especially as they are 
getting harder to find. I could do with a few 3340's and 3360's myself, just 
a couple of each as spares for my JP6 and 101. 

> Hey, Thanks for that, Ive spoken to a couple of those people already funnily enough (benden and synthparts. You think the DAC is worth having a spare one of too then? Is there one of those inside or 6 do you know?
> The guy who teched mine didnt think Id have a problem with the screens, think its been in storage for a long while- they are very bright and have no fading anywhere. I might grab one of the benden ones on the next run just in case, its great that he did that. :) Be nice if someone mass produced another run of CEMs just to future proof  us but I cant see that happening.
