the total resistance of theoutput circuit is zero, and the device will produce sustained oscil-lations. 122. Tubes Containing More than One Grid. Various investi-gators have suggested using two grids instead of one for specialpurposes. Thus, R. A. Heising, for example, used a double grid… … Fig. 231. There are various circuits in which the tubes with double gridscan be used. In one type of circuit, for example, the grid nearestto the anode is used as an auxiliary anode, while the grid nearestto the cathode operates as a controlling electrode. In this case,
