Well, instead of using a huge oddball oddball transformer, why not
use a bunch of smaller more common ones? MPJA has 24v 10a
transformers for $17.99. Two of these in series will give 48v AC and
roughly 67V DC when rectified. This is what I plan to use for my
Gecko servo system. Did I miss anything? Should work fine right? If
you need more than 10a (sounds like you do) just add additionaly
sets of whats described above. If you were to go with 3 sets of 2 (6
total) that would give you a 67v 30a supply (2.0KW) and all 6
transformers would still only cost $107. Dont seem too expensive to
me.

Mariss is the designer of the Geckodrives. Any advice received from
him should be strongly considered. He really knows his stuff. Good
luck.
