Hi, I have for sale a Ten Tec Omni A/B in good condition. I have to ask, but what is A/B? I've seen Omni listed as A, and as B, even C and D. But never as "A/B". I also know it was TT fault for confusing us naming these models (smile). Like, "Omni C, series "B". (maybe I was out that day) Ron, wb1hga "the 516 is a keeper"
