what happens when you phase NST's together in banks? Are you upping the voltage or are you upping the ma's? Just curious.

You are bringing up the mAs, or current, by putting the secondaries in phase in parallel. It is simple addition. The voltage can't be doubled by putting the secondaries in series, though, because of the fact that NSTs have two center-tapped secondaries.

I have a SGTC that uses 4x 4kV 30mA NSTs in a series parallel config for a total of 8kV @ 60mA.

Well if you removed the center tap you could probably connect them in series, but it would quickly kill the transformers because they aren't insulated for the higher voltage. Connecting them in parallel just increases the total current output.
