Thank you for your quick reply Tony!
I've already had it repaired once (electronics cracked!), and the dealers shown no interest in fixing it again (they had a hard job fixing it the first time). I don't know how I'd go about fixing the two things you suggested, but maybe I'll take the cover off and take a look...
I was interested in the manual to find out about its MIDI capabilities - I have a friend who might be interested in having it just for that purpose.
Thanks again!
