Rhodes Chroma Polaris

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.
