Back in 2013 I purchased multiple sets of Telefunken 12AX7 tubes and since then all of them have been stored in my closet never being used or even installed. Now I'm trying to clear some space and build up some money for a different project, so am putting them up for sale. I'll be auctioning multiple sets over the next several weeks. This particular set came directly from Germany. I strongly encourage buyer to add insurance. The following is an edited version of the description used by the original seller:
Original German tubes from the 1960s. Made by Telefunken in West Berlin Germany. Both tubes with <> mark on bottom. Smooth plates and B-codes of the same series (B1016201). Replacement boxes are in good condition with bright colors and detail. Tubes come from an old stock and are either new (NOS) or perhaps very lightly used.
