Description

The Svetlana™ 4CX15,000R 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 110MHz. The Svetlana 4CX15,000R has a directly- heated, superior engineered thoriated tungsten mesh filament for mechanical rugged- ness and good VHF electrical performance. This modern mesh filament design is superior to other mesh filament designs. The Svetlana 4CX15,000R is manufactured in the Svetlana factory in St. Petersburg, Russia, and is designed to be a direct replacement for any 4CX15,000R.
