Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| H.F. Amplifier | 120V | 1400 | - | - | 1.1mA |
| Operating Condition 1 | 120V | 820 | 1450000 | - | 1.1mA |
| Operating Condition 2 | 120V | 1030 | 890000 | - | 1.8mA |
Application Notes
Suitable for use in H.F. amplifiers or as a frequency changer with a separate oscillator. The screen volts should preferably be obtained by means of a dropping resistance. Suppressor grid and metallising should be connected to earth.
