Svetlana 3CX20000A7 - A7 High-Mu Power Triode
Svetlana 3CX20,000A7 High-Mu Power Triode
The SvetlanaTM 3CX20,000A7 is a high-performance ceramic/metal power triode designed for use in zero-bias, class B RF or audio amplifiers, or class C power amplifiers. 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. The low-inductance, mesh-filament basket also forms a natural extension of the cylindrical stem geometry into the active area, giving superior VHF performance.
The Svetlana 3CX20,000A7 is manufactured in the Svetlana Electron Devices complex in St. Petersburg, Russia. The Svetlana 3CX20,000A7 meets all of the mechanical interface requirements of Western 3CX20,000A7's. Prior to use, verification is necessary to ensure the maximum anode voltage specification of 8kV is not exceeded.
