Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Half-wave Rectifier (with panel lamp) | 120 V | — | 20 | — | 75 mA |
| Half-wave Rectifier (without panel lamp, tap as resistor) | 120 V | — | 45 | — | 75 mA |
Application Notes
The heater tap section (pins 4 & 6) may be used as a limiting resistance of approximately 45 ohms in the rectifier plate circuit or as a panel lamp shunt.
