Description: Untitled Document Raytheon 12AX7A 12AX7 ECC83 Black Plate Tubes, Tested, Matched Pair, Baldwin You are bidding on a matched pair of Raytheon 12AX7A 12AX7 ECC83 Black Plate Tubes, . Being used in organs, these tubes were manufactured for Baldwin by Raytheon to rigorous specifications for reduced noise and microphonics. These tubes have long (17 mm) black ladder plates, halo getters and were made in the late 1950's. These were tested on my calibrated TV-7/B. They have been tested for shorts, gas, and transconductance. The tubes tests very strong with readings of 42/44 and 40/40. Minimum is 32. They have also been checked for noise and microphonics in the phono stage of my DIY pre-amp 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. I have been selling tubes on the internet since 1998 and have been working with tubes since the early 1960's. If you have not already done so, please take a moment and look at my feedback.
