[Amps] Autotuners in Amps

I tried this in my pair of 3CX800 amplifier. Didn't like it. SWR would not 
go low enough. I was using a 1ft cable between the output of the tuner and 
the cathode. If you notice Jerry W8ZR has the tuner mounted next to the tube 
cathode. Due to a space issue, I could not fit it that close.

I ripped it out and installed a WD7S tuned input board. Easier and better.
