| GENERAL DESCRIPTION |
 |
The TH 555 tube is a high-power ceramic-metal emission tetrode with an integrated boiler. This tube can be used as an oscillator, AF or RF amplifier. It can operate up to 30 MHz and deliver a power of 200 kW. The anode, equipped with a special radiator, can dissipate 250 kW. The corresponding energy is transferred by vaporization and immediate condensation to a distilled water circuit whose temperature can reach 100°C. It can be used in a secondary circuit at a high temperature. |
