Siemens ECC88 6DJ8 audio tube - Munich, W. Germany, 1960 - Telefunken labeled - Super Strong NOS - Very Rare Note: If you are looking for a matched pair of early 1960s Siemens ECC88 tubes instead of a single tube, please check out our listing of 1961 Matched Pair of Siemens ECC88 Tubes here: https://www.ebay.com/itm/266281650331 Tubes Summary Stronger than time! This is the classic beauty in sound, admired by audiophiles for almost 60 years and will still be our top choice in the next 60 years. Particularly, the early 60s Siemens tone is considered the reference sound for serious classical listeners who need to upgrade the sound quality at the phono stage. Sound Characteristics The airy and transparent sound produced by these vintage Siemens tubes has been unrivaled even to this day. The magically extended yet never tizzy highs, coupled with the slightly focused upper mid-range, deliver a clear presentation of the entire frequency spectrum, completed by the precise and deep controlled bass. And the most defining sound characteristic of Siemens ECC88 tubes is their ability to retrieve the deepest levels of detail in sound, and these hidden sonic layers can go a long way to revealing the subtle ambient clues that help complete building a truly 3D holographic presentation. The cherry on top for this tube: the lovely blue tip, the statement of a tubes proud history of being selected as a medical tube used in mission-critical devices. The sonic differences (for the better) you are getting from the blue tip are enhanced clarity/details and ultra low noise. Appearance & Cosmetic condition Beside the world-class sound characteristics, we treasure this tube also because of its near mint cosmetic condition. Over 95% of the paint and lettering are still clear on the 63-year old tube. The Munich date codes etched on the glass is perfectly visible: #0B (# = Munich, 0 = 1960, B = Feb.) Professional Tube Testing The tube Super Strong NOS (125%+ nominal mutual conductance) on a Mercury 2000 tube tester with the following result (mutual conductance in uMhos): 15,800/15,600. Good tubes start around 7000 and new tubes (incl. NOS/NIB) 12,500 - 13,000, and 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 would 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.
