Thanks folks, antenna system is quite good here and I'm just looking for a little more power. My primary question is regarding the quality and reliability of the Ameritron amp. I can pretty much buy what I want but realize like N7WR (who actually provided a useable answer) that the difference between 1 KW and 1.5 KW is not even an S unit on the other end. I have owned other amps in the past and realize that about 700 watts peak is more realistic for a single 3-500 so really just looking for answers from those who actually own, or have owned the AL-80 a or B. Thanks.
