nge of the characteristic until the 276 THERMIONIC VACUUM TUBE mutual conductance as given by the line BC joining the points ofmaximum and minimum current becomes parallel to OA. If the mutual inductance between the plate and grid coilswere decreased, the slope of the line representing the… … Grid Volt-s - 0 +Fig. 154. Whether or not the tube will oscillate depends not only onthe coupling between the output and the input coils, but alsoon a number of other quantities. One of the important quan-tities is the amplification constant /z. Fig. 155 shows how ^u in-fluences the operation of…
