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.

Hello,

this tube was made in the tube factory "Röhrenwerk Neuhaus".
This is one of the factorys from "RFT" in East Germany before 1990, they are all closed now.
