Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Capacitor Input | 500 V | — | 150 | — | 150 mA |
| Capacitor Input | 625 V | — | 250 | — | 125 mA |
| Choke Input | 700 V | — | — | — | 175 mA |
Application Notes
For 1,600 c/s operation the same I/V relation would be obtained using a capacitor of 0.5 uF.
