Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Full-wave rectifier, capacitor-input filter | 700V | - | 125 | - | 250mA |
| Full-wave rectifier, capacitor-input filter (high voltage) | 900V | - | 575 | - | 150mA |
| Full-wave rectifier, choke-input filter | 750V | - | - | - | 250mA |
| Full-wave rectifier, choke-input filter (high voltage) | 950V | - | - | - | 175mA |
Application Notes
Vertical mounting position preferred; horizontal operation permitted if pins 1 and 4 are in a vertical plane. Filament should reach operating temperature before plate voltage is applied (approx 40 seconds) for higher voltage areas.
