Omschrijving
Ik heb verschillende buizen uitgeprobeerd in mijn hoofdtelefoonversterker en daarom heb ik een aantal setjes over. Prijzen van deze exemplaren varieren op internet tussen de 50 en 100 dollar per stuk exclusief matching, verzendkosten en invoerrechten. Onderstaand de tekst van de partij waar ik ze gekocht heb.

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.
