Hi all,
I have just unwrapped a new-to-me Casio CZ-3000, which seems to be in
excellent condition cosmetically. As I was unwrapping it, the metal
chassis gave me a pretty strong shock. I assume that was the mains
capacitor unloading into the chassis and ground. The keyboard wasn't
plugged in and hasn't been plugged in for weeks. I was wondering if
anyone knew of any common faults that this keyboard might have that
would cause this.

Best regards
