Hello Robert, all,
I really must comment on one of the points in the

An ideal transformer is a voltage source is it not? Doesn't matter
what it's rated at. If you load it up, you blow fuses.
Your point on running 500V into a 120V primary is interesting. I
have a beefy transformer producing only 5kV or so on its secondary. I
will try doubling its input voltage (while monitoring primary current
of course) to see whether the core is sufficient. The insulation
easily looks good enough on the secondary side. I had been planning
to elevate the secondary voltage by other means but this would be
much simpler.
