For what it's worth - my UP K2-X was experiencing a few flaws upon arrival 
from the UK (bought with those flaws though). One dead oscillator (tone) in 
one of the eight voices, one ground issue (all channels kept trigged 
sometimes) and one dead out (right I think). My "house doctor" as I like to 
call him fixed it in no-time. Two IC's exchanged at a total cost of maybe 5 
euro and some soldering. Every musician interested in old gear should either 
have skills themselves or find someone they can harrass with the problems. 
;)

Anyway, even if you need a pro to fix it I bet it's something _VERY_ simple. 
A dead component for the noise which might even cost cents and not dollars. 
And the outs is either a dead jack or the amplifier crcuit which is also 
very basic electronically. Don't let them charge yu too much.

But isn't the SDS-8 CEM-based when it comes to oscillators or maybe filter? 
If so, take care not to kill those circuits 'cause those chips are far more 
expensive. Not like the lame 3080 in the K2-X...
