| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Stabilizer operation | 78 V | — | 200 | — | 30 mA |
Application Notes
Much larger voltage jumps may be expected at currents below 10 mA. Total starting time (100 mA) should be limited to approximately 30 seconds per 8 hours of use to obtain long life.
