crease the amount of filament surface soas to reduce the plate resistance as much as possible. It is, ofcourse, also possible to decrease the plate resistance by increasingthe d-c. plate voltage, provided we do not operate beyond theminimum saturation voltage. Referring now to equation (26) let Zo… … Fig. 90. the ends A and B of the impedance Zq. This voltage fo can bemeasured by connecting an electrostatic voltmeter between Aand B} The secondary of the transformer T can be wound tohave as high an impedance as possible, thus impressing the highestpossible voltage Sg on the grid for a given…
