110 vs. 117, IMO same thing. most US voltages hover from 112-120 on a meter anyway.
i think you are complicating this further than you need to. i would not concern yourself with feeding any secondary voltages; your CS80 wants to be fed a steady 110/117VAC, no more no less. i would not build a unit if i were you. i would just buy a standalone unit that steps 240v down to 120v/110v, with an output that has at A MINIMUM 2X the wattage/amperage the 80 is rated for. preferably 3 to 4X.
TMK, i dont know of how a PSU that is rated for a higher current draw than it will need to supply could possibly damage a synth. has this ever happened? i could be wrong, but ive never heard of it. a properly built PSU should not have a high voltage fluctuation due to high amperage rating. if you try to draw more current from a PSU than it wants toa give, you are going to see problems. very bad idea.

Well I don't have a 110V version - the plate clearly says 117V.
And there's a lot of extra cables coming out of the mains transformer.
But OTOH the British, European and North European Specs show the use of an
extra contact block where all the incoming 3 mains wires go thru. Maybe this
contact block (or whatever it is), is missing in the other versions, which
certainly makes conversion more difficult.
And then again, the Australian Spec appears to run on 240V also, but without
that extra contact block ...
