Discussion about the Korg PolySix synthesizer

Now that the effects board is back in action, my P6 is now 99% there
at last!  I just have to fit a new battery, load the factory presets
and it should be ready for use. :-)

Unfortunately I lost the box where I had kept the screws I had
removed, so I now need to source the screws needed to secure the
KLM367, keyboard, and front panel.  Anyone know what the different
types are?

And I also have some worn rubber keyboard contacts.  I've cleaned the
gold contacts with isopropyl, and tried rubbing all the rubber key
contacts with a pencil eraser.  Some keys are still refusing to work
reliably though.  Has anyone found a method for 'revitalising' them? 
There is a rubber keypad repair kit (conductive paint) available from
www.action-electronics.com, but they only sell to the US, and I'm in
Ireland.  What method have people here used to restore contacts?

Cheers
Frank
