I try to understand why Naim power amps have transformers with two centre tapped windings. If I understand correctly the Naim configuration looks like this:
So two centre tapped transformer windings (or two transformers), ground returns into the transformer directly, and two diodes each for the positive and for the negative rail. It seems to me that in this configuration only half of the transformers power is used. So I tried to sketch a different configuration with only one transformer:
Ground returns into the transformer directly as well, and again there are only two diodes each for the positive and for the negative rail. I made a crude simulation which you can see in action here.
But I don't understand: what's the benefit of using two transformer windings as Naim does?
