Good point. I think I would prefer this also. But I already have two 
Quadras in a SO2R station. Had them for years. Presently both are 
driven by ICOM rigs, and I was hoping for an easy changeover to two 
K3s without raising new amp safety issues.

I think if I were starting completely from scratch, I might go with 
amps that are totally self-protected if they are completely automatic 
as are these Quadras. Quadra automation is superb.

Maybe, but the Quadra has been a mainline successful product now for 
around ten years. Yaesu engineers probably know what they are doing. 
But maybe they made decisions strictly for their internal product 
line just as, perhaps, Elecraft may now be doing(?).
