JJ 12AU7 A fine tube!!
As far as current production tubes versus NOS, this tube really stands up to the TELEFUNKEN 12AU7/ECC82 easily when it comes to the smooth transitions and being quiet concerning thermonics (Tube noise). For the price, I do strongly recommend this tube! I've had a pair in my HH Scott since 1997. As for being the best....??? I do love this tube...I'll just happily keep my Telefunkens in their box.
