Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| HF/MF Amplifier | 250 V | 2100 | 1500000 | — | 3 mA |
| AF Amplifier (RC coupling 1) | 250 V | — | — | 165 | 0.25 mA |
| AF Amplifier (RC coupling 2) | 250 V | — | — | 145 | 0.9 mA |
Application Notes
Used for HF, MF, and LF amplification. In triode mode (screen connected to plate), it functions as a low internal resistance triode suitable for transformer coupling in AF stages.
