Subject: Re: Faulty Keys

There is a Radio Shack in Lancaster (yes, I know, I also had to check I 
hadn't falled through a time portal!) that used to sell their own brand 
of contact cleaner in a small canister.

If anyone's in that area it could be worth checking.  Failing that I 
would probably suggest cpc - http://cpc.farnell.com

I had a few keys gone on a Master I was restoring.  Some I managed to 
get working, but others needed de-soldering from the board and replacing.
