Hello Ebayers , you are potentially "buying it now" for a pair of vacuum tubes these are NEW OLD STOCK as they have been sitting on a shelf in storage , the part number is JAN 6BQ7A they are made by SYLVANIA JAN stands for Joint Army Navy as these tubes are such good grade they are to Military Specifications , the 6BQ7A is similar to the 6BZ7 , So what we mean by merit matching is we don't have a tube matching analyzer but we do have a tube tester made by SECO that we can compare the merit test with another tube to give them the ability to work together as a pair. For us to say they are matched pair is not valid but merit matching is the next best thing. Please buy with confidence , FREE ECONOMY SHIPPING if you have any questions please feel free to message us thanks
