As far as I know these are the only authentic 5Y3 tubes being made anywhere in the world.The Sovtek and Chinese variations are not quite the same thing - though they are safe for most all amps that use a 5Y3 - the JJ supplies the correct B+ (LOWER). I haven't had any issues with the two i'm using. One can get a bad tube once in a great while but hey thats the great thing about buying new tubes from a dealer like AES ..you get one, you can send it back for replacement. No can do with 75 year old tube from Ebay..
