[sdiy] Repairing Key Contacts (OB-8)

[Bill Keys]

Sounds like my Korg Poly61, too. I had cleaned them in a similar manner - it 
worked for about 2 weeks. In the Poly61, anyway, I think the foil trick 
might work better... or it might pop something downline due to the lack of 
quite as much resistance as the carbon/rubber.... but then I could finally 
get over my hesitation and cannibalize it for parts...... hmmmmmmmmmmm

+_+_Yes, honey, I know there are 25 boxes of electronic junk cluttering up 
the attic. They will, one day, magically be transformed into a modular 
synthesizer cluttering up the attic.... www.mp3.com/OriginalSimulacrum _+_+
