Audusa (a British company)can supply excellent power cords with the "figure eight" connectors that you need. I have been very pleased with their Eupen ferrite shielded power cables. They terminate the other end with a Hubbel hospital grade plug for a nominal fee. Check them out at www.audusa.com.
Power cord adapter for video components
I have a couple video components that have cheap, removable, two-prong power cords made from poorly shielded lamp cord. I would like to replace them with something that has better shielding, like a three-pronged Belden power cord, but I first need to find an adapter that will connect to the figure-eight-shaped female end on the video components. Does anyone have any suggestions? If adapters don't exist, then does anyone know of a better power cord that can fit this type of female end? Thanks.
