**  Super-cathode drive means g1 is tied to the cathode, the screen/g2/ 
is at RF-ground, and the cathode is driven.  Typical power gain is 
roughly = to the g1-g2 amplification factor -- i.e., which is typically 4 
to 5..  .  A tuned input is needed to compensate for the wild swing in 
input Z during the drive cycle.
