RE: [TCML] Transformer Sources

 CORRECTION: I am reminded by my old fading memory that x-ray power supplies
are found in both single ended and center tapped to ground configurations.

Not sure if this will help, but the consummate builder of high voltage
transformers is Magna Stangenes. See:
http://www.stangenes.com/ 

When I was in the x-ray industry, he built the high voltage transformers for
our x-ray machines. Over 100 Kvpeak at 100 mA. He still provides
transformers to GE. X-ray power supplies are usually single ended.

Very low failure rates.

Magna is still working daily. 

If nothing else, Magna's staff or Magna himself could get you a list of
sources.

I forgot to mention that I need a one-horned, ground-referenced type. Does
anyone have a line on how common (or uncommon) these types of transformers
are in the US, at the high voltages we're looking for -- in this case,
>=16.5kVrms output (~20kVDC filtered).
