Korg DW8000, Mono/Poly, MS-20...

Can't recommend the Rock & Roll Hospital in Milwaukee (112th & 
Greenfield) high enough.  Turns out there was a small crack in one 
of the circuit boards under one of the chips.  It's now back to its 
old self again.

Unfortunately, it always had one dead oscillator and now another one 
has gone out (this results in two dead notes for every eight notes 
played in Poly1 mode).  How do you fix this?  This is apparently 
fairly common.  My good replacement DW8k is starting to lose one as 
well.  I'd like to keep these running fine...
