NOS NIB Telefunken EC92 vacuum tube. Used in many Neumann / Gefell tube microphones like the UM57, M582, and CMV 563. Measured 100% NOS with no shorts on my calibrated Hickok tube tester. Clear Telefunken diamond on the bottom. Some of the box's flaps have fallen off. Vintage German microphones deserve high quality German tubes just like this.
Usually shipped the same day of purchase, always within 24 hours of cleared payment. Please check my feedback and buy with confidence. If you have any questions, please feel free to ask, my name is Mark.
