N- -- TYPICAL OPERATION values are obtained by measurement or by calculation from published characteristic curves. To obtain the specified plate current at the specified bias, screen, and plate voltages, ad- justment of the rf grid voltage is assumed. If this procedure is followed, there will be little vari- ation in output power when the tube is replaced, even though there may be some variation in grid and screen currents. The grid and screen currents which occur when the desired plate current is obtained are incidP.ntal and vary from tube to tube. These current variations cause no performance degradation providing the circuit maintains the correct voltaga in the presence of the current variations. -N~
