"The expression, cathode drift, has to do with the random variations in vacuum tube plate current which are attributable to similar variations in emission velocities of electrons leaving hot cathodes. The fact that these random current changes appear to result from spurious drifts in cathode potential, since all other electrode potentials are unrelated to them, give rise to the expression, cathode drift...The problem with which this paper is concerned is a study of some of the possibilities of compensating for cathode drift effects in a single amplifier stage. Specifically, this paper will: (A) present a detailed mathematical and graphical analysis of the so-called Miller circuit and using this analysis, together with experimental evidence, will remove some of the limitations which the originator of this circuit initially associated with it; and (B) propose a new dual triode circuit, having only one resistor at the low voltage level, which will compensate for cathode drift while operating from a single B voltage supply"--Introduction, page 1-3.
