Lance,

I have one of the TE Systems 0532G amps.  In the manual on page 6-2
are instructions for tuning the amp's input SWR.

One more thing!  

Important! Do not drive this amplifier at more than 16w input un less
you know foe certain that your transmit power does not have a short
peak output greater that 25 watts at the beginning of TX when driving
the amp with 20 to 25 watts.  If the TX does have this anomaly the
finals will be damaged.

I had been driving mine with k3 #806 at 20 watts and found this out
the hard way.  They ain't cheap to fix....  I now drive it with 16
watts as recommended in the pink sheet that comes with new TE Systems
0532G amps.
