[sdiy] Oberheim 4-voice and Korg PS-3200 schematics and/or repair manual and paint restoration guide

[Stephan Vladimir Bugaj]

Hello.

I've got a couple projects which include fixing an Oberheim 4-voice
and Korg PS-3200, and refinishing panels on an OB-X, Rhodes Chroma,
and Steiner-Parker synthacon.  I am wondering if any SDIY folks can
hook me up with schematics and/or repair manuals for the 4 voice 
and PS-3200, and if anyone knows of any guides (in print or
online) for retouching paint on synths (or on equipment with similar
paint and metals, from which I could extrapolate)?  Thank you.

LL+P,
Stephan
