Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Triode Unit - Class A Amplifier | 250 V | 1900 | 8500 | 16 | 9.5 mA |
Application Notes
Grid bias for the triode unit may be obtained from a fixed source or from a cathode-bias resistor. It should not be obtained by the diode-biasing method because of the probability of plate-current cut-off.
