EL509 شرح
Svetlana EL509 / EL519 / 6KG6
High Performance Beam Power Tetrode
The Svetlana EL509 is a beam power tetrode intended for use in class A, AB or B audio amplifiers and for
class B or C RF amplification. Close manufacturing specification tolerances and improved high voltage
processing provides improved reliability and superior performance.
The Svetlana EL509 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 functionality and long life.
