I have an induction coil and some Crookes tubes. It can reach ~15kV. At that voltage you're into the X-ray zone. Naturally I don't take it that high. The Crookes tubes are very nice and naturally no one has them any more. I suspect there were QC problems and clueless customers who couldn't get anything to work.
