My experience with Milbert(Berning designed) is that Sylvania is the best 6JN6. Like most amps they are much more sensitive to input tube selection than power tube.
Most of the other 6JN6 are rebranded Sylvania.
6JN6 was originaly a TV sweep tube. I have never seen any foreign examples or gold pin versions.
