Here is a photo of the commercial version of the Suesskind Opus Magnum Pre-Regulator.
The PCBs have special aluminum inlays to cary the heave coils.
I am working on a more economical DIY version for the Paradise.

I have now found a coil that should be ideal.159Y Hammond Manufacturing | Mouser
It can cary 750mH, has 600mH and 11Ohm.
I choose high current capability so that a single pre regulator can drive a stereo set of Paradise.

Or, at the cost of a few volts, this one 158T Hammond Manufacturing | Mouser.

It has higher inductance and a bit of resistance that actually may help to damp it. It is cheaper and lighter, and good for 300mA.

I am using 159ZJ in similar application as per advise from John Swenson.

The 158T is not enough for two boards. For double mono it is fine.
I did not tell you before but in praxis the Paradise R3 draws over 200mA per channel despite the attempts that have being made here to calculate the current draw mathematically.

That could be '159ZA 300mH 1A 6.0ohm 500 2.50 C14H'. At the cost of mH's these go for low-resistance values, and high currents. This is needed if you do not have 'volts' to spare (so to say) or have a high current need. But if you do a new design, for low currents, you can select a transformer with a few volts more to spare, and use one with more mH's and a higher resistance, both will help make a better filter. I actualy like the higher resistance, for low current small signal circuits.

O.k. thus the 158T for dual mono and the 159Y for single supply?

Yes, i think that is cool.
I will then make dual mono pre regulators with 4 158T and the transformers i have shown.
I will use Mundorf elcaps though. I know they sound good and they are not much more expensive then the F&T. You can use any good elcap that you want though.

If you want to go economical this Panasonic ones are just fine :Panasonic Kondensatoren Serie TS-HA - hifituning24.de
