Rhodes Chroma Polaris

I don't mind doing that; I'm pretty fair with soldering station; I haven't
opened it up yet.
 
The questions I have are:
 
(a) how can I determine if that is the issue
(b) what value/type should I use? (A digikey part # would be great)
 
Also, what kind of circuit board is it?  Its not one of those 7 layer
boards.  Does the thing have to come apart completely?
 
(appreciate the help, BTW)

I have 3 Polaris keyboards, on 2 it has been necesary to replace the 
sample-hold capacitors to fix detuned voices.  The process isn't for 
the faint of heart (it requires replacing 12 or maybe even 24 
capacitors) on the boards parts cost is about $24 but it takes almost 2 
hrs to complete the repair.  Another sign of the problem are certain 
notes that seem to slide into pitch.

I think I posted more on the issue about a year ago but I would 
recommend to skilled solderers only.
