SED Factory Closure


We’re fairly certain production of the SED Winged “C” tubes has come to an end. We have purchased as much stock as available from them that was not factory seconds. We were offered factory seconds at a lower cost however we declined. We do know these factory seconds have entered the marketplace.



From our review of this EL34 tube: "If you want one EL34 tube that will do anything the Winged "C"/SED is money well spent. There is ample bass response but it is firm and controlled. The mids are smooth and the top end shimmers. Nice swirling harmonic content. The construction of the tube is outstanding and I feel it contributes to the overall performance. Lots of clean headroom from this tube with a smooth transition into breakup."

Marshall Haze Premium Pkg

by

I recently did a tube overhaul on my Marshall Haze 40 combo. What a difference these tubes make!! This amp has always been to muddy for my liking, with the stock Marshall tubes and JJ's. Now, the amp is much more alive -- tight bottom, Marshall growl, and clean, crisp highs. I changed both the pre-amp and power tubes with the Premium Pkg of SED Winged C and Preferred Series 7025... definitely worth every penny!! Thanks!

Best EL34 tube made

by

Since the old Tesla factories stopped making EL34 tubes in the 1990's, the tubes made by 'Winged C" - JSC SED corporation, are easily the best, some would say the only, satisfactory substitutes. Without getting into the sonic qualities of tubes, which are highly subjective, one can just examine how they are made and see they are superior to almost everything else. These tubes are built to be industrial grade, commercial grade, replacement parts, just as the old North American and West European tubes were. JSC Svetlana (SED) is the only "old -school" industrial electronics components manufacturer still making a few models of "receiving tubes". Too bad they don't make more types.

Much better than Electro Harmonix EL34 tubes.

I love these tubes. I wish SED would stay in business and continue making them. They last a very long time. They have a full sound. Including a lot of bass that isn't muddy. They also have a lot of crunch.

Winged "C" EL34

Rolled a set into my Cary SLI 80 integrated amp. Ran for about 5min, set the bias, ran another 30min and reset and have been listening since. After about an hour have to say these are the equal in the mids of the 6550C at twice the price. Very please. The Winged "C" tubes seem to be a great match to the SLI 80. Sad that the SED factory is gone. Hopefully, the Svetlana 'S' tubes will be very similar, which is what New Sensor is claiming.

Blackstar Soloist 60

by

Did a full upgrade on my Blackstar to include Celestian v30. Premium package tubes with Winged C EL34's. Couldn't be happier. The sound is so much warmer and the earlier breakup even on the clean channel sounds amazing. The sound is a lot more full from bass to treble. Thank you Tubestore!
