It sounds like strange beepy static and it happpens much more frequently now that I switched to an iPhone. Is there a way to stop this besides throwing my iPhone across the room?

My friend's just bought a nice new Moog Etherwave! Unfortunately, he plugged it in to the mains with just a plug converter, and since we're in Australia (240V) instead of the US, where the Moog came from (120V or something) - boom. Can we fix this? Would he have just have fried the power supply rather than the Moog itself? If so, can we just cut the cable, buy a new power supply (and transformer), and splice it on? Would that be a horrible nightmare?
