Re: [vintagesynthrepair] cleaning keyboard contacts

2003-06-23 by Richard Cohen

i live in miami where its very humid....

i noticed that on most of the metal contacts AND strips, there was oxidation 
or rust.

i am seriously contemplating shelving this unit and saving for a Korg Poly61 
that is on sale for $300.

anybody have any word on these units... tech problems, overall sound?
