TUBE 6L6


GENERAL DESCRIPTION


photo 6L6 The 6L6GC is a glass envelope beam-power tetrode intended for high-power audio amplifier service. Close manufacturing specification tolerances and improved processing provide reliability and superior sonic performance. The 6L6GC is designed to be a direct replacement for any 6L6 type.
The 6L6GC features: Design and construction based on the Sylvania 6L6GC/STR387, extra-rugged construction for use in music amplifiers--thick mica spacers and 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. 		picture 6L6
