Well, I had a choice between 12, 16 or 24 volt at the store. 16s had
1amp or 3amp. Picked up the 3 - only a couple bux difference.

16x1.4=22.4V

80,000x3A/22.4V=~10,700uF. So now I just have to find a cap close to
that. There's a store on my way to work that has larger caps, I'll
check monday. If nothing else, there's lots of 4700/50's around,
could use 3 of those for each axis.
