Nice pair of vintage Telefunken ECC81 (12AT7) tubes. They have short, ribbed plates, halo getters, diamonds between the pins, and the printing is in great shape. These came out of the same piece of electronic equipment, test equally strong, and have date codes just days apart indicating manufacture in Berlin on Sept. 23rd and 25th, 1964. See pictures for more details. I ship within the US via priority mail. Please see my other auctions for more hifi tubes and my feedback. I only sell the best vintage tubes available and guarantee their quality when received.
