hey guys-
there were two different packages with the U473, one was in a vertical cassette and the other was in a horizontal cassette. I had a pair of verticals and they were the most unspecial units in the universe. The horizontal ones that Ive used (which inspired me to find the verticals in the first place, not realizing there was a difference) fully ruled. does anyone know if there is any real difference between the two, Ive only used those four units total, so maybe I just imagined it or had a pair that just didnt have the mojo...
