Perfect matched pair of vintage Mullard 6DJ8(ECC88) audio tubes - Made in Gt. Britain - 1969 - Very Rare Note: If you are into the early 1960s sound of British made Mullard ECC88s, please see our listing of 1960s Matched Pair of Mullard 6DJ8/E88CC tubes here: https://www.ebay.com/itm/266272405275 Tube Summary No other tubes can deliver vocals like the Blackburn Mullard tubes, from ECC88 to E88CC to E188CC every variant of these can make your audio system sing like an angel, and thats a fact. These ECC88s are extremely hard to find today and are becoming the darling of every serious audiophile. Sound Characteristics The overall tonality of Mullard ECC88 tubes is warm and lively with a very spacious sound stage. Like a warm British jacket of the finest tweed, these glorious tubes have an attractive sweet warmth in their midrange and lower regions. This is how the experts on audiotubes.com describe the sound signature of British-made Mullard tubes. The top end is silky and pleasant and doesnt get rolled off. They retain a fine sense of air at the top, and the upper midrange is smooth and liquid. These tubes reproduce the human voice, especially female voices, with haunting realism. The Mitcham Mullard tubes are also known to have an attractive sparkle at the top with rich bass...now we know where that warm British jacket comes from! Professional Tube Testing Both tubes tested Strong NOS (110%+ nominal mutual conductance) on a Mercury 2000 tube tester with the following result (mutual conductance in uMhos): Tube 1: 14,000/13,200 Tube 2: 12,600/12,500 Good tubes start at 7000 and new tubes (incl. NOS/NIB) 12,500 - 13,000, and the Mercury 2000s rated mutual conductance (nominal) for new tubes is 12,500. Test result can also be seen in the pictures. In case you wonder what all these numbers mean to your sound experience, its actually quite straightforward: mutual conductance directly translates to a tubes ability to amplify sound, so the higher the numbers the stronger. Appearance & cosmetic condition Although one of the tubes has nearly half of the paint and lettering due to storage, we still treasure this pair because the very close date codes, which are perfectly visible: B9J4 (B = Blackburn, 9 = 1969, J = October, 4 = 4th week of the month)B9L3 (B = Blackburn, 9 = 1969, L = December, 3 = 3rd week of the month) Shipping Policy - Ship worldwide!
