Thanks alot for the advice, a few quick questions, the
wrist strap you refer to , is this the kind of thing I
need to get at a electronics store or can I make one? 
Otherwise simply keeping part of my hand or something
on the chasis can discharge the static?  Hmm, Thats
interesting, I noticed something about static charges
on a warning inside the organ, but never had any idea
about this...as I said I'm pretty green in this area. 
Aside from this, if a cleaning doesn't do the trick
are the parts replaceable, even by a qualified tech,
or is this a lost cause? I've seen a couple of these
for sale in ranges from 100-2000 apiece.

PS-I don't suppose you need any of those parts, but
let me know if you're interested.

Thanks again,
Ed
