When the grid is grounded for cathode driven operation is there a  
difference between cathode to grid impedance and cathode to ground impedance?  
Doesn't seem there would be.

REPLY:

My tired old eyes read his  statement "When grid current is absent, the
grid-to-cathode impedance is  nearly an open circuit" and paraphrased that 
as
"very high". Did I  err?
