Forgot to say:
That Lundahl CMC Joachim uses is a completely different beast. Much bigger core, much more ability to carry DC without saturating. That one will of course do the job.

I can measure it again, it is easy to reverse one coil. I got very good results with the connection shown in the data sheet.
For many it will be most important to find an economical alternative though.

One simple trick is to use a resistor instead of a coil. That gives a time constant that is much lower then simply amassing 100.000ths of uF.

With the shunts after all this, how audible is a Lundahl Choke going to be vs others. Why use a very high quality Lundahl and then use UF4004 over a SiC schottky? I understand and believe in quality parts, but have found that simpler circuits tend to show these advantages over more intense cirxuits such as this one. hOw do you make these decisions? Listening experience.

RC Ripple Filter Calculator

I made the Magnum Opus Preregulator for a customer that wanted exactly that including specific parts. Many non technical enthusiasts have very specific ideas about what brand and what components they want. I call that the strong placebo effect and it is not negotiable. Because i always keep one of the designs i make for my own reference i got into ownership of one. It works, itīs stable, itīs beautiful and convenient. When you read my notes i do not claim special sound. I simply did not try anything else on the Paradise.

Finding suitable inductors isn't too much of a problem.
For example: 19R226C Murata Power Solutions | Mouser
22mH, 150mA, 22 Ohms, about 2US$ each.
Would give a voltage drop of about two and a half volts. You can build CLCLCLC filter or whatsoever with this.
