Intrigued how reproducing audio and how AC power is somehow behind some if not all of the issues that are causing noise, I ventured forth and started writing why.

The answers are there, but I didn't say it's an easy understanding.

 

The 29 page attachment is hopefully a guide to cure some or all of your AC power problems and if you don't have any, you're in good luck, or it may appear next time you plug in a component.
