What happens if the load varies or if the load itself introduces hum/noise on the power line? I am thinking of how multiplexing of Nixies and/or loads with varying power draw over time will affect the noise or regulation? I don't think this will be a problem, but thought it would be good to have

RE: [neonixie-l] Re: New power supply design

If you have 600V out of a 160T winding, to get 450V you would simply put a tap at 120T. Completely isolated outputs work the same but instead of a tap, you just have a separate winding for each output. This also points the way to get a low impedance feedback network (Less noise pickup) with a
