Application Notes
Used primarily as a series regulator in stabilized power supplies. Cathode bias is recommended with a resistance of at least 10 Ohms. When using sections in parallel, cathode resistors are indispensable for current balancing. A grid resistor of approximately 1000 Ohms is recommended to prevent parasitic oscillations.
