Telefunken 12AX7 Tube, Western Germany, Hickok Tested

This is one Telefunken 12AX7 tube.   Since Telefunken ceased tube production in the early 1980s, this is genuinely a vintage German tube. 

The tube has the Telefunken diamond cast in the bottom of the tube.

TESTING:  These were tested using a pair of Hickok 533A mutual conductance tube testers.  The mutual conductance (Gm) of both triodes is written on the side of each box.  

PRINT: The print on each tube can range from strong and clear to nearly gone/gone.  Even with all print gone, the Telefunken diamond on the bottom confirms it is a Telefunken.   Each tube is printed with either Telefunken, Dynaco (Telefunken manufacture), or Fisher (Telefunken manufacture) name. 

SHIPPING:  Each tube will be in a standard tube box, and that will be inside a 32 ECT shipping box for safety.  It will be padded appropiately.  It's in my best interest for your tube to arrive in good condition, so I'll do my best to make sure that happens.

This tube ships quickly and safely from Mississippi.
