Hi!
I need help in designing a power supply with the MC34063 which will
deliver +475V @ 50mA for running a bunch of dekatrons.
I built a flyback supply for my oscilloscopes, using a National Simple
Switcher part. You might be able to do the same. The transformer
requires winding, but it's only one long winding.
You'd probably need to use an EE40 or so core size. (I think; it's been
10 years.)
The advantage of the flyback supply is that it is easy to get it to
behave, and it doesn't require a high voltage power MOSFET.
Look at this part: LM2587
