[AMPS] Conjugate Matching (again)

€  I design amplifiers for maximum power out and good linearity.  For 
Class AB1, this means relatively high anode / screen potentials and zero 
grid current.  If one does not need full throttle, the solution is to 
turn down the microphone gain control and turn off the rotten processor..
