...guys, losses are ALWAYS quadrupled!
Losses follow the V^2/R law or, more appropriate I^2*R law. And current is
average current, not peak current!
Being picky, it's the rms current, not the average. In a cap input PSU,
the rms current is often 1.5-2x the average you read on a meter, or
calculate working back from the dc power going into your PA stage. The
heating effect of that current is going to be 3-4x higher than the
average value predicts.
