[sudo-discuss] 120V isolation transformer?

does sudoroom have an isolation transformer? it's something that plugs into a regular outlet and outputs the same voltage, but it's isolating. we have a couple of universal AC converter boxes which provide 240VAC when you plug them into 120VAC but they are "autotransformers" and they don't isolate. I want us to have an isolating transformer so that when people experiment with AC-powered devices, they are much less likely to suffer a lethal shock and die. note: some voltage-regulator transformers are isolating, but since they distort the waveform in order to achieve the voltage stabilizing, they are not ideal for our purposes. thank you, -jake
