If it is truly centre tapped, the outputs will be out of phase. Only 9+9
volt transformer with two isolated windings can do that.
Once you unwind the centre tap connections from each other you have
two separate windings which can be connected in whatever phase you
choose.
True, but that's not exactly a straight out of the box solution. If you
want to go that far, I used to be able to get transformer kits, with the
HT winding safely shielded and instruction for the number of turns per
volt on the secondary. and room for more than one secondary winding, so
3 secondaries was within easy reach.

True, it requires a bit of work, but since the asking person exhausts time in usenet, I'm sure he has time avaible. Also, I have no clue where he resides. So, when asking Alternating Current questions, it's nice to know the frequency of the mains or service. While I'm sure most transformers are now designed for international use, when using a 60Hz transformer at 50Hz, you risk saturating the core.
Sure, I bet you can buy bobbins and EI (scrapless) laminations and magnet wire and design and wind your own! :-)
