Heater NotesHeater voltage depends on frequency: 12.1V (400-1000MHz), 11.5V (1-2GHz), 10.8V (>2GHz)
Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Static Values | 400 V | 40000 | — | 90 | 15 mA |
| Oscillator 2.31 GHz | 500 V | — | — | — | 100 mA |
| Oscillator 0.79 GHz | 800 V | — | — | — | 100 mA |
Application Notes
At frequencies above 400 MHz, heater voltage must be reduced to increase tube life. Operating position is arbitrary.
