Description

The Svetlana™ 4CX5000R/8170W is de- signed for audio and radio frequency applications. The Svetlana 4CX5000R/ 8170W has a directly-heated thoriated tungsten mesh filament for mechanical ruggedness to with- stand the shock and vibration encountered in military applications. The Svetlana 4CX5000R/8170W is manufactured in the Svetlana factory in St. Petersburg, Russia, and is designed to be a direct replacement for the 4CX5000R/8170W manufactured in the United States. SM
