i'm guessing a schematic isn't available for the rackbrute power supply?
i believe a friend has one, maybe i can borrow it to reverse engineer it
- hopefully nothing is potted.

as some others have said, i'm reading a lot of people saying that a
linear regulator after an smps doesn't do much to clean up the high
frequency ripple of the smps - which makes sense, that's not what the
linear regulators were designed for. so i'm very curious how commercial
designs like the rackbrute are adequately filtering this stuff...
