I have been using this combo for a number of years. I have been using the AH-4 4-pin connector to connect the 7600 to the KAT-500 Antenna Tuner.

Your Elecraft KAT-500 Tuner Protects your KPA-500 Amp – until it doesn’t – UPDATED 10/30/2019 and 10/19/2020
I have been using an Elecraft KPA-500 linear amplifier and a KAT-500 Antenna tuner with my Icom radios (mostly the IC-7600 and briefly with the IC-7300) After much research and discussion, I figured out what I thought was the best way to interconnect the IC-7600 with the KAT/KPA-500 so that the Amp would be protected...
