Beast of a tube not a desk top clock indeed.

9.7kV on the PDA is "easy" enough. The other voltages 6.1kV accelerator, 1.5kV to 2.2kV focus, -130V to -200V grid is outside the range that the CRT Tester can operate and be used as a quantitative tool as it is aimed to be. It should be able to be qualitative manner to demonstrate the tube lights up and you can get a focused spot.

That's a beast! 10KV on the PDA. I'll let Grahame chime in on whether the add-on will work with that tube, but I think it should do. I have a couple of similar 12ACP19 tubes that I'm hoping to make a clock out of....not your average desk clock either..;-)

    No, sorry the Dumont is K2249P19, not K2261P7.
