Hmm, I`ll probably use a separate filament PT with electrostatic shield between primary and secondary, and commercial mains filter before it. Then (for DC) Shottky bridge (diodes bypassed with caps), low value R, then CLC - for high-current supply. For lower current and IDHT, IC series voltage regulator.
For DHT, probably I`ll try voltage reg. + CCS, or so, but I didn`t try this so far.
There`re some examples in "Valve Amplifiers" by M. Jones...
