Just in from Ukraine: the low-noise version of the Russian military surplus 6922 equivalents. Not a lot of listening time yet, but I think I'm liking these better than the EH 6922's and the Amperex Orange label 6922's. If my ears do not deceive me, he 6N23P-EB's have the sweet midrange of the Amperex tubes, the treble extension of the Electro Harmonix, and tighter bass than either. More listening required, but so far, so good.
