Obtain input splitter and output combiner units from W6PQL. Install these into boxes with connectors.
Connect the AUX ports on each amplifier in parallel using a HD15 Y cable. If you want a full 1000 watts out on the higher bands, modify the KPA500s to remove the input attenuator. This allows a single K3 to drive both amps to full output even on 10 meters. Connect inputs to the splitter, outputs to the combiner using (obviously) equal length coax to main phase relationship. Some assembly required but not rocket science.
