Jim :

I made the documented power mod to my KX1 as I was getting too little power out, but then I
had a similar experience to yours when running off of a power supply or a fully charged SLA battery so
I built a "poor mans" voltage regulator that I can put in series with my power cable when powering
the rig from an external source. All I did was to put a couple of diodes in series, with a third that
I can switch in and out and this provides a bit of a voltage drop.  This way I can still get a reasonable
output with the internal batteries without frying the PA when I power the rig from 13.8V.
