Hi Paul,

If they are single electrode you probably can pair them for 12 kV
center tap and theoretically you could parallel as many as you
want of these pair, the only problem is parallel transformer are
not as tough as a single one of the same rating, but many of us
used farm of transformer with success especially if you use a
good filter like Terry's one.

Cheers,
