Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Triode Section | 100 V | 850 | 110000 | 85 | 1 mA |
| Triode Section | 250 V | 1000 | 100000 | 100 | 1.8 mA |
Application Notes
The triode section should not be employed with fixed bias. A high value of grid resistor is required and the triode operated essentially under zero bias conditions. Diode curves are given under Type 7B6.
