Winged "C" 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.

The Svetlana 6L6GC tube is manufactured at the New Sensor Corp. owned Xpo-Pul factory (also known as Reflektor) in Saratov, Russia.

from www.thetubestore.com - Your online source for amplifier tubes!

If memory serves me there was a legal conflict over the Svetlana name and the winged "C" name was adopted by SED to solve the issue. Until this occurred they used the Svetlana name on their tubes.

Since this question relates to tubes that are going to be used in a guitar amp this actually belongs in Instruments & Amps.. Possibly someone there will have so advice on tone and durability issues. (Moved)

The Winged "C" tubes are pretty much known as the top choice as current production 6L6GC's. I have been using several sets for years without issue. In fact, I have never had one fail out of 5 quads so far.

I use them in my Tweed Bassman & Tweed Bandmaster.

New Sensor, the people behind Sovtek, EH (Electroharmonix), and some other rsurrections of old tube brand names, bought or otherwise got the rights to sell tubes under the Svetlana name in the USA. SO they are selling their tubes from that same factory that makes the Sovteks with Svenlana on them.

In the USA, the WInged C tubes are the ones from the original St.Petersburg factory. They can;t sell them in the USA as "Svetlana" though.

SO in the USA, the Winged C tubes are the "real" Svetlana tubes.

Whether one is better than the other is a matter of personal choice. I like the Winged C tubes a lot, myself.

Quality depends on what the factory QA team is doing today. A good team can be driven to sloth by new management, or allowed to slip. Someone can also bribe a guard to tap into the reject bin and sell a bunch of **** with a great logo on it. Things change day to day.
The base problems with Soviet brands it that the logos weren't allowed to be legally registered in the US before 1990, so the "quality" brand logos can be copied. Furthermore the well known logos in the US were owned by the importer, and not the factory, so sources can change. The situation is further complicated by the Russian factories or the US importer recently has bought up quality old UK and US logos to sell under, as if the logo was important and not the construction and QA team performance. Two volume tube vendors in the US are my main interpreters of the confusing situation. Some other vendors are followed by various other customers. If you live in Europe, you're on your own at this point as to what the logos mean.

Answer: "St Petersburg!"
