Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| D.C. operation | 200 V | — | 15000 | — | 4 mA |
| D.C. operation (high) | 300 V | — | 39000 | — | 4 mA |
| A.C. operation (full wave rectified) | 170 V | — | 15000 | — | 4 mA |
Application Notes
The cathodes are internally connected in pairs: 0-1, 2-3, 4-5, 6-7, 8-9. Switching is accomplished by varying anode voltages between the two sections.
