Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Class C Telegraphy/F.M. Telephony | 3000 V | — | — | 25 | 365 mA |
| Class B Telephony | 3000 V | — | — | 25 | 130 mA |
| Class C Anode Modulation | 2500 V | — | — | 25 | 250 mA |
Application Notes
In order to keep within the temperature limits it may be necessary to direct a flow of air on to the anode seal and the base of the valve when operated at frequencies above 30 Mc/s. Below 30 Mc/s radiation cooling from the envelope is sufficient but an anode terminal connection of large surface area is necessary.
