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.

Stock is limited and our price has been raised to reflect the higher purchase cost of this final product. SED Winged "C" tubes are now be considered NOS (New Old Stock) so be sure to get yours before they are gone.

SED Winged "C" audio tubes are made by SED SPb, a division of J.S.C. Svetlana in St. Petersburg, Russia. SED tubes are well known for their quality and superb tonal characteristics.
