Hello – I have a matched pair of Sylvania Mil-Spec 5751 12AX7 ECC83 tubes for sale.
These tubes have triple mica construction, black plates and bent "D" getters. Date codes are from 1957 and 1958.
These test as NOS tubes.
TV-7/B test results: 48/45 and 45/45. Minimum is 32.
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.
