Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Class C Telegraphy | 6500 V | 15000 | — | 32 | 2000 mA |
Application Notes
The tube must not be operated without a heat dissipating connector on the filament mid-point pin. At frequencies above 30MHz, the filament pins should be decoupled to the centre tap by suitable capacitors.
