This listing is for a single vintage CEI ECC88 / 6DJ8 dual triode. A highly reliable American-made component, this valve features the classic Grey Plate construction and a Top Cup Getter, specifically designed for high-end audio preamplification where signal purity and mechanical stability are essential.

The unit has been laboratory-verified on our Amplitrex AT1000 digital tester. Using the Percentage Method, the results below display the performance of both triode sections relative to 100% factory design-center specifications (Ip = 15.0mA / Gm = 12500 µMhos).
