Really Nice Matched pair of NIB / NOS Amperex 6267 / EF86 audio tubes. Very clean and test NEW at 2,000 mhos a piece. Minimum for this type tube is 1,300 mhos and 2,000 is considered NEW.
All checked tubes are tested for shorts/leakage, emissions (mhos) GM measured DIRECTLY in micromhos, plate current (mA) read digitally, and gas/grid current. A voltage line adjustment is made after every test for best accuracy. All used tubes will come in white, individually labeled white boxes with recorded emissions and automatically tested plate current ( if applicable). Matched tubes are within the accepted 10% read value. All testing is done on a Triplett 3444 quasi-laboratory tube analyzer designed to provide high resolution results for demanding applications. My particular tester was rebuilt in July 2014 by C.G. Industries using military / industrial precision parts and FULLY calibrated to the exact specifications of the assembly line master model.
