SED Tubes
SED, one of the oldest current manufacturers of vacuum tubes, has a reputation as the world leader in vacuum tube production.
With stringent quality control and the best raw materials, SED offers the ultimate sound to musicians and audiophiles alike.
SED EL34
The SED EL34 is a glass envelope power pentode having a plate dissipation rating of 25 watts with convection cooling.It is intended for audio frequency power amplification service in either pentode, ultralinear or triode connection and single or push-pull/parallel applications. The SED EL34 has an indirectly-heated oxide cathode, which may be DC operated for the absolute best hum/noise performance.
SED KT88
The SED KT88 is a glass envelope beam power tetrode and is manufactured at the SED Spb factory in St Petersburg, Russia. It is intended for audio frequency amplification and close manufacturing specification tolerances and improved processing ensure reliability and superior sonic performance. The SED KT88 has been designed to be a direct replacement for any KT88, KT90, KT99 and 6550.
SED 6550C
The SED 6550C is a glass envelope beam power pentode. It is intended for ultra linear audio frequency power amplification service. Close manufacturing specification tolerances and improved processing provide improved reliability and superior sonic performance. The new SED 6550C features: increased peak cathode emission from new cathode materials; stable operation from extended processing and ageing; gold-plated grid; new tri-plate anode; single-piece beam forming electrode; precise grid/screen alignment; improved vacuum processing; and comprehensive static and audio amplifier testing before and after ageing.
SED 6L6GC
The SED 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 SED Spb factory in St Petersburg, Russia, and is designed to be a direct replacement for any 6L6 type.
