@d4b81373 Yeah, I don't get out anything like as much as I used to.  Small child will do that! But let me know next time you are out in Chester and I'll shout you a beer and shock you with stories of piss poor high voltage practice 

 @d4b81373 Ask me over a beer. 

 @d4b81373 We run them 5 a time in parallel to run 100kW 915MHz magnetrons, so we have a fair few about the place.  I think the 20kV supplies were at least being looked at when I left, but it is a decade ago. 

 @d4b81373 I've recently been involved in setting up a test stand for some 20kV power supplies that will deliver a full amp!  It's been interesting, to give it an extremely euphemistic gloss.
