What is the input impedance of a 6sn7? [message #9596]

I mean the grid to ground impedance not the grid resistor. I assume this impedance is in series with the grid resistance. I have always considered a tube grid to be an open, aside from the interelectrode capacitance.....Tube cad says no. What I'm trying to do is install a high pass filter between the output of my preamp and the input of the power amp.

Thanks...Tre'
