Hi everyone!

A friend and I are designing a Pulse Width Modulation Amplifier that will
pump out 800 watts ( 200 watts / 4 channels) and have come up with some
specifications for the whole circuit. (assuming 8 ohm speakers for load)

It seems obvious that we need a power supply that can put out 40 Volts at
20 Amps and be highly filtered.

Does anybody know how to build such a beast of a power supply?  Is it possible
to buy one? If so how much?  Has anybody got any schematics?  Any know where
is the best place to get these higher power handling diodes and capacitors?

We need any help that people can offer..... We have the rest of the amplifier
designed.... Just need the power supply now....    :-()

Thank you!
