I think that the plan is to cascade the two transformers in series, 
using the 600V tertiary winding, so the "high" transformer's core is 
floated at 4500V.

These things have a fair amount of leakage inductance, so the output 
current is limited.



I built a similar cascade, using 4 transformers: two cascades, with a 
center ground, and it's in many respects like a giant NST.
