NOTE: TYPICAL OPERATION data are obtained by actual measurement or by calculation from published characteristic curves. To obtain

the anode current shown at the specified bias, screen and anode voltages, adjustment of rf grid voltage is assumed. If this procedure is

followed, there will be little variation 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 anode current is obtained are incidental and vary from tube to

tube. These current variations cause no performance degradation providing the circuit maintains the correct voltage in the presence of the

current variations.
