re repeated failures - have you got a ups in line - they really don't like voltage variations, what mission critical computer kit would you ever think about running without a ups? the UK power supply is pretty solid but I still travel with a ups and make a judgement decision every gig I go to as to whether to use it or not (theatres generally no, hotels maybe, outdoor events always.) re spares - have you talked to music group directly in kidderminster? I would be very surprised if they were not selling post warranty parts. their prices have always been reported as reasonable too. incidentally, I am given to believe it's one, non region specific power supply in the x32 units, i.e. not 110 or 240 but both.
