    I have one. I’m new, I have a tech, getting a gen.
    I have a iCOM 7200. If everything worked and was hooked up right would this be a good pairing?

      The radio should drive the 70V OK. Just so you understand that is a 50 year old amp and if it has not been overhauled, may need some capacitors replaced in the control circuits. The tube is quite rare so be VERY careful not to overdrive it, watch the grid current all the time !!!
