Untitled Document RCA 5751 Black Plate Triple Mica Mil-Spec Tubes - Matched Pair, Tested
You are bidding on a matched pair of RCA JRC 5751 12AX7 ECC83 triple mica audio tubes.
These tubes have triple mica construction, dual steel support rods to help minimize microphonics, black plates, "D" getters. They were made in the late 1950's.
Th...ese were tested on my calibrated TV-7B. They have been tested for shorts, gas, and transconductance. The tubes test very strong with readings of 50/52 and 48/48. 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 lookat my feedback. All tubes are 100% guaranteed good on arrival. These are great tubes for your new audio gear, guitar amps and vintage stereo/audio gear. Thanks for viewing my auction.
