>So the question comes down to this:
Well, I'd agree. My assumption on input impedance is based on the
average driving impedance of a grounded-grid 4-1000A. This is about 110
Ohms. The input capacitance for the 4-1000A is about 27 pF. So I took
two 220 Ohm resistors, put one to ground on each cathode pin and put the
27 pF cap to ground on one of the pins.
I am fairly confident because I had matched stuff up before pretty well
in the past and most of my circuits needed little changing. But you do
raise a good point, so we shall have to wait and see!
