[Amps] Need rectifiers for X-ray supply

[Borislav Trifonov]

Hello gentlemen,
I was using four GE KR-9A kenotrons (probably pre-1960s) to rectify 120 
kV at (pulse driven average) 50 mA for my DIY X-ray setup.  Didn't 
bother immersing in oil due to running at much lower power than what the 
tubes are obviously designed for.
Last night had a big argument with the girlfriend and she broke three of 
the tubes... I almost cried.
I'm wondering if anyone here has leads to other suitable high voltage, 
high power tubes so I can rebuild my bridge.  I've only found one other 
KR-9A willing to part with its owner on teh intrawebs this far.
