John,
You are correct to say "some surge protection devices shut the system down on low voltage." That is what Surge Guard does according to their literature. That is why I choose to use another device, i.e., one that doesn't do that. The one I choose will only capture the spike, but it will not respond to low voltage. Since that is true, I choose to follow the plan espoused by pparamore.
His system will capture a high voltage spike but allow low voltage to pass to the autoformer for an appropriate boost. Therefore, the whole system will be as protected as possible including the autoformer. Since the autoformer has built into it some level of surge protection, that gives a certain amount of redundancy on spike protection. Guess I have been hanging around NASA too long. Kinda like the redundancy.
