| Description |
Silica envelope transmitting triode. Silca valves were introduced around 1920 by Mullard. Silica withstands high temperatures without softening as glass does. This feature made possible the construction of relatively compact power tubes with electrodes operating at high temperatures, so granting efficient radiation cooling.
Anodes were made by basket woven molybdenum ribbons. Filamentary cathodes were of tungsten or thoriated-tungsten for increased emission, as in this case.
- 5.0 kV max anode voltage
- 2 kW continuous plate dissipation, 2.5 kW intermittent
- 2.0 A max emission
- 20 Mhz full ratings, 30 MHz maximum operating frequency
