I recognize the tube, a distinctive small-plate 12AX7. I've seen them with all sorts of brands and countries of origin, all of which I'm sure are fiction (I've still got a bunch of them labelled Radio Shack!). It's actually a very nice tube in the right circuit- the Berning TF10 was designed with them.
