Come to think of it, that power wouldn't be wasted at all. I just
remembered a neat little power splitter circuit I designed a few years
ago; using that I can tap off a signal for the amp and the rest can be
rectified, filtered, and fed back into the power supply. So nothing is
wasted except in conversion.
