Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Heptode | 250V | 870 | 1200000 | - | 3.8mA |
| Triode | 80V | 5300 | - | 16 | 4.5mA |
Application Notes
The triode oscillator should be used with a parafeed tuned anode circuit. If squegging occurs, grid leak resistance may be reduced to 25,000 ohms. A peak heterodyne voltage of 9 to 10 volts is required.
