    That might not work either. The NST probably has a center tap ground,
and one side of the MOT is grounded, so this makes it difficult to connect
these in series because you end up with several kV between the cases of the
transformers. Furthermore, it would buy very little because the transformers
are poorly matched- the MOT would only add 2kv to the output of the NST
which would most likely not be worth the efforr IMHO. Better to just use
either the NST or the MOT.
