Perfectly balanced vintage Telefunken E88CC/6922 Tube - Ulm 1961 - Super strong NOS Note: If you need a pair of early 1960s Telefunken E88CC tubes instead of a single tube, please see our listing of 1962s Matched Pair of Telefunken E88CC Tubes. Tube Summary Behold the illumination at night, write down how your music sounds the moment these tubes start glowing and keep your notes forever. The finest in the fleet, Telefunken E88CC is unequivocally the supreme commander of the entire E88CC/6922 tubes family. This gorgeous tube is from the Ulm, Germany production - the most sought after Telefunken sound. Sound Qualities Like any other Telefunken tubes, these E88CCs are very pleasant to listen to: liquid, euphonic, with a slightly warmer midrange than many other German tubes, which makes your sound experience smooth and non-fatiguing, and all that happens on a unbelievably realistic holographic sound stage, where everything feels bigger, wider and taller. Sound texture can be felt through infinite levels of details, laying on top of each other, both in depth and in width. So your quest for superb sound clarity can end right here. Lastly, it never gets old to say that no other brand is even close to these when it comes to low noise - Telefunken tubes are extremely quiet just as legend has it. At this level of the game, the only possible upgrade path from these tubes is the 45° angled support version of Telefunken E88CC, of which we do have a wonderful pair from the same year listed here: https://www.ebay.com/itm/266252618250 Appearance & cosmetic condition Beside the world-class sound characteristics, we treasure this tube also because of its excellent cosmetic condition - over 95% of the paint is still intact and the Ulm factory date code is perfectly visible: U6101301M (U = Ulm, Germany, 1 = 1961) And of course the diamond mark on bottom - the symbol of the best sound one can ever find on E88CCs. Professional Tube Testing The tube tested Super Strong NOS (120%+ nominal mutual conductance) and perfectly balanced on a Mercury 2000 tube tester with the following result (mutual conductance in uMhos): 14,900/14,900. 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.

Return Policy - Please READ carefully First of all, returns are acceptable as long as you are reasonable. Soundlumia sets extremely high quality standard for the products we deliver. Tubes we sell are guaranteed to work because we run professional tests and sound evaluation before they are approved for listing AND before we ship them to customers. So the defective item case doesnt exist and please do not bother trying - this type of returns will NOT be accepted without proof that tubes do not work and we will open a dispute with eBay. Sound experience is a very subjective thing, and lets be real its not that easy to run into compatibility issues between amps and tubes (so that one wont fly, either.) Please contact us to work things out before submitting return requests claiming item is defective or item not as described. We would really appreciate your respect to the professional work we have done (sourcing, testing & matching tubes, evaluating tube sound, sharing our sound experience with you, packing and shipping) to make these wonderful vintage tubes available to you at reasonable prices. Secondly, if you are a tube roller looking to game the return system, Number One STOP. Soundlumias founder is a seasoned sound professional who has advised orchestras and music studios in sound production in USA for over two decades, and knowing sound is the minimum skill requirement of our team. No tricks here please. Abusive behaviors will be reported to eBay immediately and negative feedback will be left to your account - thats guaranteed. We have already reported several abusers and eBay has ruled in our favor the dispute cases. We are more determined than ever to continue working with eBay to help rid of these unprofessional, unjustified, unkind, unfair and unacceptable abuses that are detrimental to the eBay marketplace, the vintage tubes market and the audiophile community.
