Do you still test light bulbs?

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.
