I've been thinking: how much better would pure (regulated) DC be? For a
given magnetization, would the current be less? Or would the heating be
less?

A previous Reply said that the DC voltage only has to be about 5% of the
AC voltage to reach the same level of magnetization. In that case the
200v secondary would only need 100v DC. I'm using more than that, but
I'm wondering if it's because the unfiltered DC has so much ripple.

Anyhow, I could build a 100v regulator, but would it be worth it?


Why regulate it? A simple filter would make a huge improvement.
Connect the cores in series to drop the DC voltage in half.
