There are a couple of custom 50/60Hz units out there for that purpose that provide a low voltage winding for the logic and a high voltage one for the nixies. > I was thinking to use a high freq. transforcer (because is smaller) and > basically rectify the output.

Look for a 1000Ω:8Ω output transformer. They got used in the old Radio Shack kits with a 1-transistor blocking oscillator to produce high voltage. Würth Electronics offers some 1:1:1:1:1:1 transformers that can be configured in various ways. Possibly paralleling two windings as the primary, with the remaining four windings in series as the secondary, would give you some voltage boost with an off-the-shelf part. For more step-up from commonly available parts, ordinary CCFL transformers offer ratios from 1:50 to 1:100. One last idea is to get an ordinary inductor with plenty of turns on it to serve as a secondary, and wind a few turns on it to serve as the primary.
