No power reduction is required -- let's do the simple math. The KPA 
draws about 10A at 120v keydown. That 12v (probably 13.8V) supply 
shouldn't draw much more than about 2A when the K3 is driving the 
KPA500, because the KPA needs less than 30W to get to full power. The 
13.8V supply should draw no more than about 2A with the K3 barefoot at 
full power keydown.
