I couldn't stand it. As I looked up from playing my guitar and saw that lovely spool of the new 600V Duelund DCA12GA PolyCAST tinned-copper tone wire, I just had to do something! I decided I really needed to cut a set of 2.5 meter speaker cables off the spool, and then try them as speaker... Read More »

First of all I want to thank you for being patient with me. As some of you know, my Mom, almost 94 years of age now, has been going through some rough times health-wise. Getting her to and from doctors, hospitals, trying to help her out generally, and spending quality time with her has been... Read More »

I thought the Hammond's aluminum top plate painted in Altec green like the 511-B horns would make for an attractive nod to Altec tradition. However, the large... Read More »

I really want to thank Frederik Carøe for being so generous as to indulge a resistor idea of mine, and then going way beyond what I imagined to handcraft a truly amazing resistor, which Frederik has humorously dubbed the "Jeffistor".
