Casio CZ/ VZ/ FZ - Pro Series

I read an earlier post by someone with a sick CZ-1.  I have the same 
problem.  I hadn't played the CZ in years (my bad) and when I went to 
try him out again (now that his sounds are cool again) there is a 
bunch of fuzz coming out.  The sound fades in and out with fuzz and 
crackle.  I would like to repair this myself.  After all... I can't 
imagine paying shipping for that fat synth just for repairs! Someone 
mentioned working on the amp board?  Can I do this myself?

Thanks!

Eric
