Hello – I have a matched pair of 1950’s Raytheon black plate 12AU7 ECC82 tubes for sale. These test as NOS tubes. These tubes have long (17 mm) black ladder plates and halo getters. They were made in 1958. TV-7/B test results: 100/100 and 95/100. 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 Dan Nelson 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.
