I knew I had seen a circuit somewhere, and now I found it on the Internet too - it was in my "Markus: Sourcebook of electronics circuits, McGraw-Hill" which is a collection of schematics from different magazines, and here is the link: http://www.seekic.com/forum/22_circuit_diagram/24850_500000_PPS_SCALER.html there you can see what voltage and anode resistor that is used with the EZ10A dekatron. The same anode rsistor and voltage is used for the first stage EZ10B, but usually EZ10B is driven by 580V and not 500V like in this circuit.
