Yes, I was also surprised at the 220 vac requirement. No, the console
won't be happy at 208 vac. I called up the local electrical supply company
and they had a small read-to-go autotransformer to fill the bill, about 6
inches on a side for about $150, and it works fine. Try your local
supplier, and call if you need more details.
