A web search turns up ONE country on Earth running 100v, Japan. The world being a big place rendered tiny by the internet, where anything and everything can be found (a German man looking for people willing to be killed and eaten had several applicants) and knowing how people love to prove others wrong even if it means missing the whole point, saying there aren't any was a bad idea. I stand corrected.
But, calibrated (what I said) and regulated (what I never said) are two completely different things. Seriously. You could look it up. The 5% regulatory variance allows the NOMINAL (means, you could look it up, in name only) 120v to vary as low as 114v. Whatever. The question was, do stepdown transformers affect SQ. The answer is yes. And do I even need one? To go from 120 to 100? To avoid damage? The answer is no.
