I recently bought an amp with a pair of 2A3 variants showing Svetlana Winged C logos on the bottles. No one I know that works on tube amps has heard of these tubes. They tested as 2a3's and sound quite nice.
Has anyone heard or even heard of these tubes, and if so, what do you know about their lineage? Any info would be appreciated!

Made by the original Svetlana tube manufacturer. They are an almost direct replacement for the 2A3. Quite a few Russian tubes are clones or replacements for European and American tubes, and this is one of them. Probably quite old stock as well. They haven't been made since the early seventies.
