€  As I understand it, Norm started off with the G2DAF article and 
circuit.  When the distortion proved to be problematic, Norm began 
experimenting with the screen circuitry in hopes of reducing distortion 
level.  How could you possibly know all of the different screen circuits 
that Norm tried to clean up his amplifier?.

€   The thing that set Norm's amplifiier apart was rapidly changing 
screen-potential, moderate grid-current and moderate distortion.    When 
Norm eventually held the screen potential constant and he stopped driving 
the grid into the positive region,  distortion was no longer legion.
