Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Rating 1 (1500 c.p.s.) | 7500 V | — | 1800 | — | 75 mA |
| Rating 2 (80 c.p.s.) | 7000 V | — | 1900 | — | 50 mA |
Application Notes
The Heater must be switched on for 15 seconds before the Anode Voltage is applied. Surge limiting resistance may be obtained in the distributed resistance of the transformer. All Maximum Ratings are absolute values.
