Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Pentode | 250 V | 11000 | 50000 | 26 | 40 mA |
| Triode | 250 V | 13000 | 1870 | 25.8 | 46 mA |
Application Notes
The valve is eminently suited for use as a triode connected cathode follower amplifier having a low output impedance. No positive DC grid current should be allowed to flow. Not recommended for use as a Class B or C amplifier, or as a frequency multiplier.
