I'm not a professional electrical engineer by any means. However, I am a college student that's barley one semester away from graduating with a major mechanical and minor in electrical engineering.

I want to say that I have no idea how this tweak works. For that matter, I don't understand how just about ANYTHING out there works electronically. All the wonderful equations, theories, etc. that everyone states (and I use in class on a daily basis) are simplfications of observed phenomena.

Everything interacts physically. Your neighbor's washing machine is affecting the current flow in your audio equipment. So is air traffic over your home. The fillings in your teeth might be doing something too...but to such a small degree that I would bet that it could only be measured by the best instrumentation, if at all--but the fact is that it has some sort of effect.

I'm suggesting that APM's tweak MUST have some sort of operation theory, becasue it works. Gravity exists wheter you belive in it or not.

Try this experiment. Get a multimeter, and set it to read AC voltage on the smallest scale. Put it on the floor with leads attached to the meter, but not touching anything. The numbers jump around, right...but there's no circuit. Grab one lead with your hand, and I'll bet that you'll record some sort of voltage change. Still, there's no circuit, so why is there a reading?

Now, in your circuit diagram, there's something left out. That's the capacitance between the two conductors in the lamp cord. For a DC signal, this might as well be ignored. However, for high-freqency A/C , there is a completed circuit (the capacitor) from "A to B" as you put it. If you wanted to calculate or measure this capacitance, I'm sure you could. I'm also sure it's *very* small.

Perhaps this is a contributing factor as to how this tweak works? Perhaps the device acts like some sort of antenna? I'm not sure. However, I am sure that, in my case, and for several of my friends, this thing works.

I can't explain why. However, I can certainly appreciate that it does. Who cares why? I just care that my computer is a lot quieter than it was before.

I'm sorry if this came across as offensive to anyone. I'm just doing my best to understand how this works--becasue I know that it does. I suggest that people try this before telling others that it doesn't work.

Enjoy the music.

Allan
