Cable Comparator

As I remember it was Wireworld who had that device but I don't think they were selling them. They were using them for their own comparisons and research. I think.

I think this is what you remember. Here's an article on the original comparator and its inventor, David Salz, of Straightwire and Wireworld.

Brushro - to answer your question - the Cable Comparitor was made by David Salz at Wireworld cables (www.wireworldcable.com). I doubt that they are still available as it was quite a while ago, but IF one can be gotten, David Salz would know how to go about it.
