I tested the tube in my Telefunken Gavotte 5353W. The Gavotte uses a EM84, but since the pinouts are the same, and the specifications are similar, the EM85 could be tested in the radio. It was tested in daylight with the fan pattern showing clearly. The tube label was very faint to begin with, barely showing the M85 part of EM85, and a few letters of Lorenz. After handling the tube for the test, I can no longer make out M85 and can barely see a little bit of the last part of Lorenz. You can still see the bottom of the Lorenz logo(the arrow points to it) and the word Germany. $35 plus shipping.
