You only need a single 10k resistor in that circuit. In your picture, remove the one at the top with the yellow wires, you would be connecting the desired cathode directly to ground.
Additionally, you have the tube connected back to front. The circuit you need is as follows: HV output to 10k resistor 10K resistor to Anode Cathode to Ground - Richard On Saturday, 13 March 2021 at 16:28:44 UTC [email protected] wrote: > Hi everybody, > > Many thx for your quick replies, and sorry for my late one.
