REPLY:

Pay attention, Carl. We ARE discussing the Super Cathode circuit. Here's the
entire paragraph that I quoted one sentence from:

"There are obviously major flaws with the super-cathode drive concept, when it
uses a capacitor divider. Grid current causes grid-to-cathode impedance to
constantly vary. When grid current is absent, the grid-to-cathode impedance is
nearly an open circuit. Grid-to-cathode capacitance dominates the upper half of
the divider, and everything appears to work as planned."

You did say your 'ol eyes were having problems, but try and find the words
"super" and "cathode" in the above.  :-)
