Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| RF Oscillator | 400 V | 2200 | 11400 | 25 | 25 mA |
Application Notes
Anode and grid connections are brought out through the bulb for very low capacitance. At wavelengths greater than 14m, a plate voltage of 500V is allowed if dissipation stays below 10W. At 4m, plate voltage is limited to 250V.
