Our friend an fellow Audiogon member Joe Sanders (Joe's tube lore over at AA) is a good friend and has a DIY version that is splendid. Perhaps he will post data here about values and how to construct. I think I have the data in an old email along with photo's.
The idea is the same as the Quiet Line devices that plug into your wall socket. It does work and the Quiet Line is great at less than $30.00. I have about a dozen Quiet Line's plugged in and around my audio system, having used them for more than a decade.
The DIY version uses better quality caps and higher value and should be a nice upgrade. I've never gotten around to ordering the plastic boxes and parts to build one, perhaps this will inspire me :^).
