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.
