I have a 80v 12amp power supply from Antek

I got it for the Keling steppers I have which I was told take 80V

I am using Gecko 203Vs so they should be able to handle the voltage I think?

Also, what is the simplest way to step down the voltage from this power supply? The only thing I could think of would be to get another transformer and put it on the output side of the toroidal transformer before the full wave bridge and filter capacitors.

What do you guys think? Thanks for the help.
