Exactly.

You're talking about RECTIFYING DC voltage from AC. the only differance between 50 and 60 Hz is that you'll need a little more filtering, not more regulation. voltage regulators usually come after the powersupply caps, and hold the supply voltage at a constant voltage. They don't allow "sag" unless the supply dips unususally far during a brownout etc.

using an amp designed for 120 at 220 will blow the amp up, period. DON'T EVER try that...
