Dear Members, Great was my surprise when I  open a Telefunken EM80 new in box and to find the TFK logo in front face of the tube!!  .  Now I should see in close-up the TFK logo and in the background the signal intensity in the magical eye.  Someone knows if the Telefunken factory delivers guarantee by this tube still?  Kindly regards, Bruno.
