The problem seems to be that after all this dialogue, that so
many of the responders simply don't stick to the basic
premise that different phases by definition have timing
differences. Simply reversing the way of using a phase does
not make it a different phase. The timing stays the same.

Ok I get what your saying.. But do you understand what a phanse

difference
is?? It is timing like you said..

Here is an explanation using audio waves. Maybe you can get
what I am saying.

By your definiton, a 'Push-Pull Output Transformer' is two
phase.

It IS two phase; that's the whole point. (At least on the primary side.)

Then a Williamson 'Ultra linear' output transformer is four phase?

http://www.pmillett.com/file_downloads/stancor_ul_schematics.pdf

See page 4 for a sample schmatic.

I looked at your Stancor PDF. Why in the world would you think I'd think
that transformer is 4-phase???

[btw, the schematics are on pages 2 and 6]

OK, I'll play along here. On page 6 they show an output xfmr with 2
taps. But of course that has nothing whatever to do with phase, as you
damn well know, because the output is referenced to one of the OUTER
LEGS OF THE TRANSFORMER (see that "COM" on the bottom?), so the output
is simply one phase. I was talking about a center-tapped transformer
where the two sides are referenced to THE CENTER TAP.

So again, how does a center-tapped transformer secondary WHERE THE
OUTPUT IS REFERENCED TO THE CENTER TAP (i.e., the center tap is
grounded) NOT generate two separate phases? Please 'splain that.
