Q About Inductors and Hum Control

[Paul Marossy]

Just a dumb question: In A/B box for example, can you use a small inductor in series with the connections to ground to avoid hum problems? My idea is that inductors resist changes in current, so you could avoid ground loop hum by using inductors rather than trying to isolate grounds and all that. Is this possible?

EDIT: I remember seeing someone's DIY A/B box and I seem to remember it used inductors in series with the ground connection(s). I can't find that page now, but that's what I remember, and that's where I got the idea...

fwiw, in the DOD a/b box there is a resistor (15 or 51ohms forget which) in the ground line. Resistive ground isolation I guess that is what it is.

I suppose that could work, too...

Never mind. It's an idea, but not one that will work very well. An audio transformer is the better way to go...
