I must be missing something in your words Bob (DGN). If, after operating at some plate current and RF output using a PI network, and now you want to reduce output, why would reducing the loading and re-dipping the plate capacitor (to return to resonance), become "non-resonant" unless the words that Bob (MYJ) used, "maintain the dip" means that he doesn't re-dip the final after a loading control change. Since the beginning of (my) time, the last thing I always do in a tune up procedure is to dip, or check the dip, of the final.
