Vintage Synth Repair

Hello. I just recieved an Arp odyssey,black with gold 
lettering,bought it through ebay, but of course turned up d.o.a!
I have a couple of questions,wich i hope someone will be able to 
answer. First thing i did was cut off the american fuse and 
replaced it with a european one, and went out and bought a 
transformer. Fired up the unit, but nothing happened. Mine has 
no light in the power switch,so it´s a bit difficult to find out if its 
actually on or not, but i plugged headphones in the Low output 
on the back, checked the front panel to see if sync and keyboard 
were on,as well as output volume ,but i didnt get anything. 
What i´ve done so far: took off the slider caps as they were 
dirty,and cleaned them, unscrewed the unit,took some hay out of 
it, but actually i was surprised to see that apart from the hay the 
unit looks quite well (hhmm). All the keys are still in position and 
looking good, i´m taking out some of the dust inside and 
cleaning it overall. As nothing happened at all when i plugged it 
in,i assume the problem is something to do with the power 
supply. Checked the fuse and found out it´s actually soldered on,
but it doesnt appear as its blown. does anyone have any idea 
wich things commonly could go wrong ? Any help would be 
greatly appreciated.

hello freaks,
i just bought an arp odyssey III synthesizer in a good cosmetic condition.
the problem is, the owner hasn't played it for about 20 years.
so there is just a lot of dust and some sort of oil in the sliders. many
of the filters don't work, and everytime i turn it on, it sounds quiet different
from the last time, but i didn't change anything. i allready cleaned it a
bit, but i cant' get into the sliders.
however, there comes sound out of it, so the basics are working.
it's quiet difficult to find an synthesizer-expert here in switzerland, so
i just thought i will repair it by myself.
what do you think, is it possible? what would you recommend me to do? any
tips or instructions? 
i would be very pleased for help!
thanks a lot

If someone has put oil in the sliders, it is likely it is 
short-circuiting and you may need to replace the sliders. They will be 
tough to find i'd say...

Yes, you can get into those sliders and I think you need to. But...be 
very carefull. There is a chance you end up with dead sliders..

Other possibility is that you send those sliders you want repaired 
over to me. But it won't be cheap ...You'll find my address in the 
links section under 'Saint Eric's Analoge Synthesizer Reparatie 
Atelier'.

Regards,
Eric.
