Poly 6 troubleshooting

[Benjamin Woenig]

I have just aquired a Korg Poly 6 that requires a bit of a service.

The biggest problem is that one of the voices is dead. What is the
best way to find which voice is is not working. If it is the SSM
filter that is dead, what are the chances of obtaining a SSM2044?

Also, they keys require a fair amount of pressure in order to trigger
a note, so I am assuming I have 61 dirty contacts to clean... any
recommendations for this horrid task?

Thanx :)
