Matched Pair Amperex 6DJ8 ECC88 Vacuum Tubes Valves

This matched pair of Amperex 6DJ8 / ECC88 dual triodes was tested on our Paul Hart-modified Triplet tester for shorts, gas and transconductance. There were no shorts or gas. They measured 8640/9440 for Tube One and 8800/9120 for Tube Two where minimum (65%) is 8160/8160. These are premium tubes made for Hewlett-Packard's exacting demands. Their silkscreening is pretty good for both. They are labeled "Made In Holland;" have sutured tops and O getters. I have played them in my Alan Eaton single-ended 45 amplifier (with adapters; not included and they sounded great. WE HAVE SCORES OF THOUSANDS OF VACUUM TUBES. IF IT'S NOT LISTED, WE MAY HAVE IT.
