Hello – I have a matched pair of Raytheon 5814A 12AU7 ECC82 Black Plate Mil-Spec Tubes for sale. These are NOS and new in the box tubes. These tubes have triple mica construction, black plates and "D" getters. They were made in 1957 and 1958. TV-7/B test results: 100/100 and 105/105. Minimum is 56. They have also been checked for noise and microphonics in the phono stage of my Fisher 800B and are dead quiet. All tubes are tested on my calibrated TV-7/B or on my calibrated Hickok 539C. All of these tubes have been tested for transconductance, shorts, gas, leakage and life. All tubes meet or exceed manufacturer published specifications of transconductance (Gm) for the specified tube type. All tests are tested twice – prior to the listing and prior to shipping.
