EL519 - High Performance Beam Power Tetrode

Download the EL519 datasheet PDF. This datasheet also covers the EL509 variant, as both devices belong to the same high performance beam power tetrode family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • Increased peak cathode emission from new cathode materials; Stable operation from extended processing and aging; Gold-plated grid; Precise grid/screen alignment; Extraheavy glass envelope for ruggedness; Improved vacuum processing; Comprehensive testing before and after aging. The Svetlana EL509 is manufactured in Russia at the Svetlana factory and is designed to be a direct replacement for any 6KG6 or EL509. The strict manufacturing and quality controls at the Svetlana plant assure functionali.
