Audio Beam Power Tetrode
SV6L6GC Shown
The Svetlana SV6L6GC is a glass envelope beam-power tetrode for high power audio amplifier service. Close manufacturing specification tolerances and improved processing provide improved reliability and superior sonic performance.

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
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.
