Hello,
I joined this list because I have just get damaged my Korg Poly
61 (also
another RK100 controller seems to have the same symptoms) . It
gets
crazy when powered on, all lights flhasing and emiting strange sounds,
I
think it's related to capacitors, as you are talking about. Please
if
you have a service manual and could send me a copy, it would be
great.
About the diode, I'm sure is not a problem to replace for any
other not
being exact, and probably the capacitor could be replace for the
more
closely one 470 or 500 are easy to find), I use to replace this kind
of
things in other machines and all they worked. If not, you always can
do
some combination , as you probably know, in serial
combination,
capacitors give you the the result of
(c1.c2.c3...cn)/(c1+c2+c3...cn)
Regards.
