Thanks for confirmation.I was recently researching possiblities of making an ultra small PSU with <1W output (nixie watch project) and I'm currently stuck with CEEH54 and CJ5143 and I'm toying around with them.However, I've found another little gem to order and play with:https://www2.mouser.com/ProductDetail/TDK/ATB322515-0110?qs=ivTIEzcXi41rlQuCra1Ohg%3D%3D
So it is possible to get much smaller transformers designed for step-up applications. I wonder how much power can be drawn from PSU built around so small transformer. This will probably require designing a LLC converter just to decrease losses in the transformer. With it I could lay two Z5900Ms side by side and hide the converter between the tubes!I think that for a full scale clock with 6 small tubes there would be a need of building two of PSUs working for three tubes each, but that would allow to go even thinner.There is also (mentioned in the datasheet) a 2,4mm height version, still significantly thinner than most transformers I've seen.

Actually I have another choice for make it thinner with 4mm transformer, but it seem to be nosence compared to 5mm.
My first version is only designed for fly pins nixie tubes with tube PCB adapter, I never thought my last version will compatible with NL-5441 and NL-841 tubes, still 6mm base, the end of tube pins almost touch the bottom pcb board.

I'm wondering how the power supply is made - judging from dimensions of your NCH8200HV power supply, fitting that transformer isn't an option - or am I wrong? Or is it a boost converter on a flat inductor with voltage doublers?
Anyway, this is the thinnest clock base I've ever seen. In fact, none comes even close - second thinnest was 20mm thick (it was fully wooden, though). It is really impressive.
It reminds me of bonsai trees, where very low pots are chosen for aesthetic reasons - it helps exposing the tree itself. It works here, too - even the small tubes are not dwarfed by the base.--
