Went to the Fry's today and got myself one of them `Heavy-Duty Step-up/Step-down Power Transformer` that can do 110->220 and vice-versa (they didn't have any transformers that take 120 as an input). And of course when I tested it at work, the output was 240V... So I'm wondering, is it safe? Anyone tried using European amps with such transformers in North America?
