Details:

Original box and warranty sheet are in great shape.

Contacts are heavily tarnished, but should clean up with a little effort. I don't have a way to test this tube, but I am sure it is unused because the filament is perfect and the anode button is smooth and flat with no erosion whatsoever. The 20X672 is the Ge equivalent of the 4B36.
