There was an old patent using two neon sign type transformers back to back.

I can't imagine how that could be worth patenting. Many patents have no value.

The problem with isos, you get higher voltage with no load than normal, and
droop 10-20% with load..

It would take an unusually tiny transformer to be that badly regulated.

"Neon sign transformer"
They are DESIGNED to be baldy regulated.
High voltage to strike the initial arc, then sag down to
a sustaining voltage.

Same design with fluorescent ballast transformers.

Both are designed for a specific purpose, not to be used in some
*******ized lash up.
