I use a mux in front of an HP34401 multimeter that auto ranges and so can read from 0.1uV to 1kV. It was just easier to display 6 decimals on the quickie UI I wrote tonight. -- You received this message because you are subscribed to the Google Groups neonixie-l group. To unsubscribe from

Nice! I'll definately buy some if you will sell it in the future (near future I hope)! Will it be possible to get 300V from this power supply without a voltage doubler? From what you write, and looking at the picture, this looks like a standard switcher which doesn't use a transformer -

Really nice with 400V output voltage! Regarding isolation, some circuits are easier to build if the different high voltages needed are isolated from the low voltages (digital and/or analogue) and in the case with Russian Dekatrons like A-201 (Polyatron) it is a lot easier to design a circuit
