Hey, I purchased quite a few tubes to get the right ratings for my 3 channel build and found that there are many different styles of the 19J6 tube.
My experience is heavily with the RCA tubes and then a few Sylvania tubes.

[size=medium]AGE (Oldest to Newest)[/size]

#3 - #4 - #1 - #2 - #5
[size=small]Sylvania: [/size]
#7 - #6 (don't know which of the two is the oldest)
[size=medium]
Personal Favorites: [/size]
#6 - Most Detail / Soundstage, but the treble can be shrill at times - by far the best in the group and very revealing
#1-#3 - Very good Overall Balance with Good Clairty (makes even bad recordings sound OK) Lowest Noise of any Tubes, very consistent quality from tube to tube
[size=medium]Please Post if you have experience with these tubes or you have found another type of the 19J6.[/size] ( I think that GE, NU, Raytheon, and Westinghouse brands, but haven't found any to buy)
