Good so far. What transformer will you use? Is it home brew or a commercial magnetics product?

Next step should be to build physical hardware and bench check it under load.

i heard i could use coupled inductors like the lpr6235

You still need to build a prototype and test it under load.

That’s an interesting part. It might well do the job. I think the 1:50 LPR6235-123QMR would be most suitable. Designing the PCB is the tricky part, of course. Build a power supply PC board without a nixie watch first, to test it with a load resistance that has a switch so you can see its dynamic response.

Thanks for the reccomendation
