Svetlana 4CX12000A - A Radial Beam Power Tetrode
Svetlana 4CX12,000A Radial Beam Power Tetrode
The SvetlanaTM 4CX12,000A/8989 is an air cooled power tetrode designed for audio and radio frequency applications. It is particularly well-suited for use in VHF FM broadcast transmitters in the Band II 88-108 MHz frequency range and has full performance ratings to 250MHz. The Svetlana 4CX12,00A/8989 has directly-heated thoriated tungsten mesh filament for mechanical ruggedness and good VHF electrical performance. This modern mesh filament design is superior to the old hairpin design of the 1950's.
The Svetlana 4CX12,000A/8989 is manufactured in the Svetlana factory in St. Petersburg, Russia, and is designed to be a direct replacement for the 4CX12,000A/8989 manufactured in the United States.
