High Performance Audio Beam Power Tetrode

The Svetlana SV6L6GC 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 SV6L6GC is manufactured in the Svetlana factory in St. Petersburg, Russia, and is designed to be a direct replacement for any 6L6 type.

The Svetlana SV6L6GC features:

  • Design and construction based on the Sylvania 6L6GC/STR387.
  • Extra-rugged construction for use in music amplifiers--thick mica spacers and extra bracing reduce microphonic effects and resist mechanical and thermal shocks.
  • Increased peak cathode emission from new cathode materials.
  • Gold-plated grid and extended processing and aging for stability and reliability.
  • Tri-plate anode for superior dissipation.
  • Precise grid/screen alignment.
  • Comprehensive static and audio amplifier testing before and after aging.
  • May be operated in inverted position--base fits into socket clamps in Fender guitar amplifiers.
