The Svetlana 6L6GC is a glass envelope beam-power tetrode intended for high-power audio amplifier service. Close manufacturing specification tolerances and improved processing provide improved reliability and superior sonic performance. The Svetlana 6L6GC is manufactured in the Svetlana factory in St. Petersburg, Russia, and is designed to be a direct replacement for any 6L6 type.
Construction - Glass. Cooling - Convection. Useage - Beam-power tetrode intended for high-power audio amplifier service. Features - Design and construction is based on the Sylvania 6L6GC/STR387. Microphony and mechanical/therminal shock reduced by adding thick mica spacers and extra bracing. Increased peak cathode emission from new cathode materials; gold-plated grid; tri-plate anode for superior dissipation; precise grid/screen alignment.
