|Another book to look for is the one from the MIT/RadLab series which
|deals with vacuum tube characteristics. My uncle showed me the
|section he wrote, which happened to deal specifically with
|electrometer tubes and characterization of the grid current for them,
|so I know it's in there. Sorry I can't give a more exact reference.
My copy, "Radiotron", is Fourth Edition, 1952 ;-)
