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

after i cleaned my polysix contacts i had problems with a few remaining  iffy keys....  even recleaning didnt help.... what DID wirk was simply hitting the key dozens of times in a row...eventually the occasional playing key became a consistantly playable key... this worked on all the iffy keys i had. .......  now all is fine ...This is true.

Frank,

If you drop me a private message I will gladly drop a couple out for 
you and measure them. The ones that hold the KLM-367 down are the 
same as the ones used for the other boards attached to the wooden 
chassis. So providing they are all not lost you should be able to 
find at least one example. The others are metric metal screws, but 
I'll have to measure them!

If isopropyl doesn't work for me then I use a product called 'Mykal 
De-Solv-It'. You can get this in the UK and Eire from Radio Spares 
(RS). I have found that sometime the laquer from the green parts of 
the board gets onto the gold contacts. A vigourous rub with Mykal and 
you will have a very clean set of contacts indeed. Also please ensure 
the black switch contacts on the rubber parts are mat black with 
no 'mirror' image on them. I can send you photographic examples if 
you wish.

Cheers,
Andy
