Poly 61 info?

[Ben Stuyts]

Hi List!

This weekend I bought a Korg Poly 61 at a flea market. They asked around $100,  
but I got it down to $50 (fl 125,-) ...  I know it's not really a higly rated  
vintage synth, but I guess for $50 it's okay, right?

It basically works, but it needs a good cleaning, and perhaps some replacement  
pots. Some of the switches bounce a lot, so I hope those can be cleaned. A lot  
of keys don't work unless you jiggle them, so I guess the contacts are dirty.

It didn't come with a manual. I was wondering if there is any way to restore  
the factory presets?

Any other tips? Interesting Poly-61 web sites? Anybody have a manual? Schematics?

Thanks and kind regards,
Ben
