Siemens E88CC/6922 Audio Tube - Telefunken label - West Germany 1968 - Strong NOS Note: If you need a pair of late 1960s Siemens E88CC tubes instead, please see our listing of 1969/1970 Siemens E88CC/6922 Tubes Matched Pair here: https://www.ebay.com/itm/266274273460 Tube Summary Stronger than time! This is the classic E88CC/6922 beauty admired by audiophiles for over 50 years and will still be their top choice in the next 50 years. Look no further if you are seeking the greatest E88CC/6922 tube sound. 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, which is completed by the precise and deep controlled bass. And the most defining sound characteristic of Siemens E88CC 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 build a truly 3D holographic presentation. Appearance & Cosmetic condition Beside the world-class sound characteristics, we treasure this pair because of its pristine condition - nearly 100% of the paint is intact, and the date code stamped on the metal tag inside the glass is perfectly visible: A4 8G (A4 = E88CC, 8 = 1968, G = July.) Professional Tube Testing The tube tested Strong NOS (110%+ nominal mutual conductance) on a Mercury 2000 tube tester with the following result (mutual conductance in uMhos): 13,300/14,000 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.
