S34 system

I got to meet Max today and see the S34.

Nice machine is fair condition. His problem is that it's wired for 208
and from what I could observe all the transformer primaries are limited
to the 200V range (208/220/240). Can some one up on S34s confirm that?
All the power comes from three feroresonant transformers (CVTs) which
explains the 580v warning (across the resonating capacitor).

It would seem the only way to power it off 117v line is tansformer
of the 1000-2000va size. I suspect the smaller will work as this
machine while complete is not "loaded". It's biggest disk is an
internal 69mb 8" with what appears to be a DC spindle. Anyhow for
power it expects a single phase 208 L-L connection so a auto transformer
may do it.

It's been a while since I've seens linear regulators or possibly low
voltage switchers of this size.
