Svetlana 3CX2500F3 — Medium-Mu Power Triode
Svetlana 3CX2500F3/8251 Medium-Mu Power Triode
The Svetlana 3CX2500F3/8251 is a high-performance ceramic/metal power triode designed for use in amplifier, oscillator, or modulator service. A modern mesh filament is used, replacing the old-fashioned hairpin construction. The improved mesh filament design ensures better mechanical rigidity and long lasting concentricity of the filament, providing enhanced linearity, less noise, reduced warm-up variation and longer life. Flying leads are provided for filament and grid connections to eliminate the need for a socket in low-frequency RF and AF modulator applications.
The Svetlana 3CX2500F3/8251 is manufactured in the Svetlana Electron Devices complex in St. Petersburg, Russia. Svetlana has achieved the improved performance described above with exact replacement compatibility with the 3CX2500F3/8251 manufactured in the United States.
