The JJ 802S a replica of a very special ultra low noise very long lived Telefunken tube. The 802 is a 12AU7 or Ecc82 what have you. As far as current production tubes go and your preferences I would consult Jim McShane who is a sponsor over on Audio Asylum's Tube Asylum. I know he is pretty happy with the Gold Lion tubes which are said to be on the warm side of neutral.
If you want to try nos I recommend Amperex ECC82s . In particular one formerly excellent, drop in sub, is the highly desirable 7316, which have become very expensive and widely copied (lots of fakes). Your best bet for NOS and the better subs is to rely on a good dealer.
