I don't have a schematic for the HTAA-16W-A, but Clint is correct --
each of the three supplies is a bog-standard LM723 circuit. I am
attaching a reverse-engineered schematic I found on the net of a
different Power One supply as an example. I hope I've made it small
enough to get through the server without list-minder approval, in case
Tom is still away.
