Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| H.F. Pentode | 150 V | 1100 | — | — | 3 mA |
| H.F. Pentode | 150 V | — | — | — | 2 mA |
Application Notes
Used only in the first position in the set where the signal voltage is small. As an anode bend detector, smooth reaction is almost impossible to obtain.
