Power xformer primaries backwards?

[A Jedi]

For some reason I can't visualize or conceptualize what happens with secondaries and rectifier if the AC to primaries is reversed. It seems like the rectifier shouldn't care but I'm not sure. V+ and V- should stay the same regardless of AC polarity on primary(ies) correct?

It’s the diodes that determine the polarity of the DC output. The phase of the AC has nothing to do with it really.

That's what I figured thanks.

The rectifier and filter capacitor circuit is symmetric for both the "up" and the "down" parts of the sine wave,
so reversing the relative phasing of the primary winding (or the secondary) would make no difference
in the DC output of the power supply.
