Someone could come out with a circuit board for a single configurable
voltage and decent noise specs. Use three of them for a Tbolt.
It is really easy to use the transformer from an old microwave oven to make
your own power transformer - the HV and the 110 volt windings are on
separate parts of the core so it is a matter of a few minutes to hacksaw off
the HV winding and you can use standard household THHN wire for your new
secondary - wind ten turns, measure the voltage and use that to figure how
many turns you actually needed.
If someone came out with such a bare board, I would buy 20 of them just to
keep around for projects.
