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.
