Why does an amplifier need a power supply?
The power supply in either a guitar amplifier or in a professional sound amp reduces the 110v alternating current to a direct current. Also it reduces the voltage that can be used by the speakers, usually 12+ volts. Also if there where no power supply and there could be a possible way of reducing the voltage that could be used in the same was a direct current, you would here a constant phasing type noise from the current alternating. A power supply unit converts power that can be used in correctly in sound frequencies.
