Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Quadrature Filament Excitation (20-50°C Mercury Temp) | 15000 V | — | — | — | 2500 mA |
| In-Phase Filament Excitation (20-50°C Mercury Temp) | 15000 V | — | — | — | 1500 mA |
Application Notes
The tube must be mounted vertically base down. Provisions should be made for adequate air circulation. Condensed mercury temperature should be maintained at 40°±5°C for most satisfactory operation. Filament should reach operating temperature (30s) before plate voltage is applied.
