Rhodes Chroma Polaris

I had to mix-and-match slider boards between 2 of my Polaris keyboards 
after I lost Slider Depth function on one.

An interesting note is that the "donor" slider panel from a Polaris II 
has differnt slider pots installed.  They use a different PCB footprint 
and don't wiggle side-to-side like the older part.  Also the action is 
much smoother.
