This is a new old stock female connector that fits the tonearm that came on the Empire 298, 398 and 498 turntable. These tonearms were called the 98, and 980 tonearm.  I have CNC machined a nice American walnut shroud to fit it. This shroud is attached with two #6-32 stainless button head screws. While the main reason for offering these is so people can make an affordable cable for the 208, 298, 398 and 498, I also think they offer the ability to make a cable with better wire and RCA jacks. The connector comes with instructions and an Allen wrench.
