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 with isolated power supplies than those that use a common ground. Isolation can of course be made with optocouplers for the other signals but in some circumstances the original design used transformers as isolation between the different voltage levels to make sure that it was easy to drive the Dekatrons/Polyatrons. Right now I am using small Traco switchers to isolate the high voltages from the low voltages and also optocouplers in some cases in combination with this. There might be other ways of doing this but I am trying to follow the original designs to get things to work before I start to experiment with other solutions, and in some caes I want to stick to the original designs and not use modern components except for the power supplies which I don't regard as part of the original circuit (I also want to minimize power usage and weight). /Martin
