Rhodes Chroma Polaris

I purchased a Polaris off the analog list less than a year ago.  The thing 
is in almost perfect shape except that it appears two of the oscillators 
won't come in tune.  The auto-tune says they are, but they aren't.  You can 
tell when you play a scale, the 5th and 6th notes will just be off by a 
couple of tones.

The guy who had it before said he just shut off those oscillators when he 
used it, but that tends to take a way a bit of the polyphony.

Now, some people have told me the problem is the row of caps.  I pulled it 
apart, saw then, priced them etc.  But I don't want to resolder a bunch of 
these things (I think there were twelve) and then find out it didn't make a 
difference.

Also, the machine seems to have "forgotten" everything.  There are no 
presets, or patches, or anything.  I assume those can be reloaded?

I can do basic repairs myself (i.e. replace caps), on the other hand, I'm 
not adverse to sending it to someone if they actually know what they're 
doing.

Any advice?
