Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Triode section | 200 V | 2000 | 13500 | 27 | 4 mA |
| Triode section | 100 V | 1800 | 15000 | 27 | 2 mA |
Application Notes
With a plate resistor of 0.32 Megohm and a cathode resistor of 16000 Ohm, an amplification of 18x is achieved at supply voltages of 100-200V.
