Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Pentode Connection | 300V | 9000 | 500000 | - | 10mA |
| Triode Connection | 150V | 11000 | 3600 | 40 | 12.5mA |
Application Notes
The 6AH6 is a miniature sharp-cutoff pentode. Its high transconductance and low capacitances adapt it to use as a wide-band amplifier or as a reactance tube. For triode connection, connect grids 2 and 3 to plate. Grid number 3 has practically no control characteristics.
