Think it through, it is an ANTENNA tuner (matching circuit).  You disable all of them along the path (BYPASS), EXCEPT at the antenna connection.  

It is presumptive 50 ohm to 50 ohm resistive at each stage, no tuner required, except for the antenna.

> I have a KX3 and a  KPA100, both with ATUs. Can I power up my TX via addition of a KPA1500, assuming I upgrade my antenna (Buckmaster 300watt OCFD 8 bander)  to the  3000 watt version ? If feasible without risk of blowing up anything, and  assuming the KPA 1500 also has a built-in autotuner, at what stage should auto tuner control be established?
