We have been taught to tune up at the power we plan on using, but that 
is more for efficiency than anything else IIRC.  But now when we are 
looking at power out and not efficency, there are after all those who 
run class A to get multi KW out, what about IM.  Lets say you tune up 
for a very comfortable 1500 out, but for some strange reason decide you 
can get by with just 750, or half that amount. You are already tuned up 
for 1500 out, so all you do is reduce the drive to get the 750 out.  
What does that do to the IM on the output?
