Description

The Svetlana™ 3CX6000H3 is a highly reliable ceramic/metal power triode designed for use in amplifier or oscillator service. A modern mesh filament is used, ensuring better mechanical rigidity and long lasting concentricity of the filament, contributing to longer life. Flexible leads connect to the filament terminals and a mounting flange provides the grid connection. The flange provides a convenient way to mount the tube. The Svetlana 3CX6000H3 is manufactured in the Svetlana Electron Devices complex in St. Petersburg, Russia.
