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.
Stock is limited and our price has been raised to reflect the higher purchase cost of this final product. SED Winged "C" tubes should now be considered NOS (New Old Stock).
The NOS Winged "C" (SED) EF86 / 6J32p tube is a glass envelope miniature pentode intended for high quality audio preamplifier service. It is designed to be a high quality direct replacement for any EF86 tube or 6267 tube type.
