	Correct.  A correctly designed power oscillator has enough, and only
enough, feedback to drive the grid to the correct current for maximum
power output.  When you have gotten everything tuned right, you will
have achieved that condition.  Only problem is how to get to that
optimum tuning, particularly when dealing with a non-linear and reactive
load.  Good luck!
