Smps for audio tubes voltages.

Hi there

I want to build a smsp for high voltages and filament.

Need 2 x 120 volts 250 mA 1 x 350 volts 100 mA 1 x 6.3 volts 5 amp and 1 x 12.6 volts 5 amp
or I can make one 18 volts 10 amps and use regulators for filament ofg tubes, the 10 amp is
nice for bigger tubes for experimenting.

I do not now what to use, resonant LLC is best for low radiation, tubes are sensitive. or a flyback
who is most used for high voltages, can someone tell me wat is the best way.

I did use exellentIT for flyback transformer calculation but I get uge current in simulation, and voltages
does not match. Maybe there are more ways to calculate transformers, I use transformers from pc supply,s
so there is a need to get them working right is maybe difficult.
.

thanks.
