Default TL494 transformer less ps for tube amp

I have been trying to design this my self but progress is
slow. Need help!
I need an 120vac to 400 to 600vdc 500ma
and 6.3vdc for heaters @ 4amps..... transformers
less design.
I am really interested in tube amps now, but not the
big and heavy ps transformers.

I've not heard of many tube amps with switching PS designs, they likely cost more than the transformer itself and in my mind the complexity probably negates any benefit of lighter weight.

bulky iron is just a fact of life with tubes. Even if you avoid the PS transformer somehow you will then have output transformers(unless you build an OTL? unlikely) and PS chokes.
