| 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.
- 12 kV max anode voltage, derated to 7 kV at 20 MHz
- 4 kW continuous plate dissipation
- 1.6 A max emission
- 20 Mhz aximum operating frequency, 7 MHz full ratings
Mainly intended for industrial RF heating equipment, usable in communication transmitter sets.
