Big dumb, like Hammond IE types or **** expensive handmade but still dumb types?
decent yes
will you get it cheap or you'll go Kosher route.........
Hammond, as far I know is proper engineering quality work
choose appropriate one and you're good
now, depending of context - remember you can have sort of normal way (one choke per rail) or you can have common choke, which is two windings on one core, covering 2 rails
be it bipolar (plus, minus and GND) or "single rail" (one rail and GND) - you can use common mode choke
in later case just take care where GND is really established
as always, ZM Omni is sayin' - GND is state of mind

And common mode hence means more noise cancellation, but need more current capability I presume. Will dig into it a bit. Thank you ad always MZM! Will be interesting to see what PSUD shows wrt inductance values etc and voltage requirements for the tranny. I believe that everyone should build an Aleph, and a choke input supply. At some point at least 
Another question: have you ever built and used a choke input supply, and is it worth it?

I did and it is worthy, well
Anyhow - what's most beneficial is to keep eyes open and brain ready, so you can spot little tiny details in anything of reach, then you can think of
majority will be total and utter waste of time, be it really not useful to anything of your interest or simply way above your head
but with time, level of your ignorance is going to slightly decrease, thus level of possibly useful details is going to increase
I'm pretty much in Mu state - my ignorance is on exact level with anything I see around so I can't use anything

Yes, still a lot to learn, and building something like that will surely be good learning. A bonus is more transformer efficiency, right? And less or same need for snubbers?I did and it is worthy, well

Needs several readings, but useful, as old stuff usually is!

Something like this? Haven’t modelled it yet so dunno if inductance level is way off or not, but asking principally.
5H @ 500mA but no graphs for inductance at final load current, but most FW constructions will pull that amount pretty quickly, which is a bit important so there is less need for very overrated caps and most important to get above the critical level.
Do you mean this posting? And the first pic? https://www.diyaudio.com/community/threads/ludef.369990/post-6997306
Not bad:

But @ 10A rated current inductance will be low @ normal FW load currents.

All need modelling of course, and needed values will depend also on dual mono or not. Expensive but probably worth it, we all love blackness.
