This requires scoring your electrical plug blades with notches. I use an x-acto knife or similar to cut mine, and I try to cut a fairly good, even notch. Be careful not to let body parts get in the way in case your hand slips, because the metal is slippery, and pressure (in a back and forth sawing motion) is required to cut a decent notch. Using a sharp blade means less chance of slippage and better results. Try to carve a clean, even, single line across the blade (it requires staying in position). The method illustrated here is similar for both US and UK plugs, and the diagrams show the 3-notch method (see Note).

US: Cut one notch on the center surface of one plug blade (outer or inner, not both). Cut two notches around the center of the other side of the blade you cut the first notch in (the single notch you cut on the first blade should be about in the centre of the two on the opposite side of the blade). In the standard methods, nothing is done to the third prong of a grounded plug.

UK: Notches are cut in a fashion similar to US plugs, but in the insulated area. See diagram.

Note: There has been doubt and different reports among Beltians and co. representatives, as to what the proper procedure is (since obviously, there can be many variations of this). So I experimented a bit (total test time: about 15 minutes) to try to clear it up for this page, and these are my findings:

You can get benefits from doing 1, 3,  and 5 notches (also 9, but that may be a bit overdoing a good thing, making things too smooth). The best overall is probably 5 notches total . Below are instructions for each.

1-notch: Carve one notch on the outside of one blade. That’s it.
3-notch: See diagram.
5-notch: Do the 3-notch method on one blade (as in diagram), then add two notches to the outside of the second plug blade.
9-notch: As with 5-notch, but 3 more notches are added to the ground pin of a 3-prong grounded plug (notches can be side by side, they do not have to go around the round pin).
11-notch: Don’t be ridiculous.

Belitsts note: If you have PWB’s “Sol Electret” product, it is most advantageous to apply it to the plug blades afterward.

Technical notes: I didn’t want to leave the confines of my computer room,  so these tests were done using the computer’s cd burner as the playback device, with my AKG phones plugged into the computer’s sound port as the listening source. The plug used for the experiment was a 3-prong grounded plug from a pedestal fan next to the computer desk. It was never plugged in. So then. If you are the skeptical sort, but you have discovered that this technique really can improve your sound, and you have convinced yourself it does so by messing with the flow of electrons…. (and if you are thinking that way, I don’t blame you, I was under the same mistaken impression for twenty years!). Then try the same experiment on an unplugged device.
