Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Class A Amplifier | 250 V | 5250 | 800 | 4.2 | 60 mA |
| Push-Pull Class AB (Fixed Bias) | 325 V | — | — | — | 40 mA |
| Push-Pull Class AB (Self Bias) | 325 V | — | — | — | 40 mA |
Application Notes
Resistance in grid circuit should be less than 0.5 megohm for automatic bias and 10,000 ohms for fixed bias. Replacement for 6A4G is not recommended without circuit adjustment due to cathode connection.
