€  Because ZSAC controls conduction angle.  In the RL formula, the 
constant in the denominator changes with Class of operation --  i.e., 
conduction angle.  See *Care and Feeding ...  * for more info.  .

€   peak anode current is limited by the emissivity of the cathode.

€  beats me.  One guess is grid placement.
