Vintage Synth Repair

Hey dude,

Your in luck! I just took some pictures of my studio set-up yesterday 
so I've up loaded a fat photo of the front panel into the photos 
section. Keep clicking on the photo till it shows it at full rez' 
(two clicks)
I love my SH'! It's a helluva a lot of fun and it's got such 
character! But goddamnit, It stopped working! First the keys were 
really noisy, even with all the oscillators off. Then the oscillators 
stopped working all together, exept for a  very faint unpitched 
squeal. Does anyone know what might be causing this? Is it relatively 
easy to repair, or am I better off taking it in to be repaired? Any 
help would be wicked!

Cheers,

Wotzit.
