I've tried a lot of stuff/solutions but so far I haven't found a single power supply, that is sold, that produces these voltages directly, all need an external voltage doubler/tripler. With the kit from Michael Moorrees you can add a doubler/tripler very easy, look a bit further down on his webpage here: https://threeneurons.wordpress.com/nixie-power-supply/hv-supply-kit/ (an external solution, he also has a larger voltage multipler for use with for instance the IEE NIMOs) or with the Tayloredge PSUs you can do something similar but there is no pin available so you'll have to solder a wire to get to the pulse output: https://www.shop-tes.com/1554-hvps-horizontal-smt-high-voltage-low-noise/.
I could make a new PCB and add all components on it (even thought about making a cut-out that would fit for the original PSUs from Moorrees or Tayloredge and just add the other parts) but I'd really prefer a PSU that had it all on the same PCB. I have understood that it is a real challenge to make a PSU with these voltages unless they use a doubler/tripler design, but I still hope that someone is up to that challenge. There is a linear voltage regulator here: https://www.bartola.co.uk/valves/2012/10/20/600v-feedback-regulator-finished/ that I haven't had time to build and test yet, but it looks very good and you can follow the design on the blog. /Martin On Monday, 2 November 2020 13:45:55 UTC+1, Paul Andrews wrote: > > > Hi Martin.
