Well Larry, if we heard something from Dave now, I'd be inclined to trust him, because after digging deeper into the site, it appears that he's passed away. So, I'd modify my "is" in the previous reply to "was".

The site rambles on nonsensically that his thing was to "improve electron flow", and this is accomplished with "quality" capacitors. So, this is another one of the capacitor scam sites which imply that more or better capacitors can work some mysterious magic.
