KPA100 Upgrade Problem

Jim Brown-10
In preparation for the K60XV I just finished, I had to upgrade my
KPA100. It involved changing a few resistors, adding two jumpers, and
replacing the firmware. It's now shutting down when I go into tune
mode (with the KAT100). I smelled smoke, and R21 in the KAT100 shows
signs of overheating. I've pulled it back apart and looked for
shorts, wrong component values, or other problems, but found none.

Any ideas?
