Best 6V6 tubes out there, period.

They are Russian equivalents of 6V6GT. Do note that the 6P6S tubes were made by two different factories. One was the Reflector factory located at Saratov, other is the old Svetlana or the SED Winged "C" factory located at St. Petersburg. The one made in the old Svetlana factory with the Winged "C" logo are the best.

Here's a thing about them, I buy them in pairs or quads. They cost me around $8 to $10 per tube but when it comes to reliability and longevity they curb-stomp those overpriced New Sensor and JJ 6V6 tubes that are sold in the market. In terms of quality they are up there with some of the best NOS 6V6 tubes. Just remember to go for the ones with the SED Winged "C" logo.
