The Audioasylum recipe uses Belden 19364, which you may find difficult to find in smaller quantities (say less than 100 feet). A division of Belden (Volex) makes a pre-terminated cord, the Volex 17604 (search for Volex on line-easy to find them and distributors) which comes in a couple of different lengths. The 17604 is the Belden 19364 cable, 14 guage, shielded. You can usually buy small quantities of these cords as opposed to the raw cable. You can buy a 10 footer, I believe, and cut it in two and reterminate-cost for two cords about $10-$12 plus your plugs. I use 3 of these terminated with a Hubbell 5266 male and a Bulgin iec and they are a major improvement over stock cords but not in the same league as the Cardas Golden or the Blue Circle BC 62 that I own, which cost about 15 to 20 times more.
Looking to build power cords.
I'm interested in building my own power cords. I have been able to find manufactures to purchase high quality plugs from, but am lacking resources for the cable. And I'm not realy sure what to look for as far as spec go for the cable, ie best guage to use, twisted thin cable strands or larger stiffer strands etc. Any help would be great. thanx
