drlowmu,
I'll review your PSUD2 graphs and get back to you off forum.
My flywheel filter is about what I could build with the parts I have on hand.
Have a good day,

IIRC, you said that was your day job. Do you work in a factory or at a distributor? And I'll bet those light bulbs today are LED or compact fluorescent?Now if at a factory, why not discuss your power supply design with some of your engineers at lunch? After all, an LED or CF lamp contains a switch mode power supply. That is an LC filter on the output.
All the math and theory to design an LED or CF power supply can be re-applied to a linear audio amp supply. And as SMPS design is far more complicated than brute force linear supplies, I'm sure your engineers have lots of superior knowledge on power supply inductor theory.
If I wanted to know more about choke input power supplies, an SMPS design engineer is probably the best source of knowledge you will find today.

I'm working in an R&D lab with mechanical and chemical engineers for the last 3 years.
Mostly setting up and running life tests on various products made of composite plastics, rubber compounds and metals. Then I document test results and send data sets to the engineers for analysis.
The company outsources electrical engineering work to Germany.
One of the engineers and the other guys in the lab know I do the tube hobby, but they are clueless to help me out.
Except for the help I get from the forum or online, I am on my own to learn anything new.
Not always such an easy task.
