>From the pdf describing construction details it appears the anode plate is phosphorized, and both the cathode potential and filament current are highly regulated. Additonally the device is temperature controlled by heating elements and further encapsulated in a seconadary thermionically regulated shell. The precison of temperature regulation quoted, 0.0001 de.g C, does not look credible, however. Regards, Horace Heffner
