Hello – I have a matched quad 1950's Tung-Sol 12AX7 ECC83 tubes for sale.
These are original issue. Not the current crop of Tung-Sol tubes which are not made in the USA. These have 17 mm long gray ladder plates and a D getter. They were made in the mid 1950's. Two of the tubes are mil-spec.
TV-7/B test results: 48/48, 52/50, 48/48 and 46/46. Minimum is 56.
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 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.
Please e-mail me if you have any questions.
