Soundlumia's Opinion How many times had they done this together 60+ years before? Your logo, my tube, or vice versa. Perhaps countless times to those who witnessed the making of these incredible tubes but to most of us perhaps fewer times than we have even heard of. Yet every collaboration brought nothing less than the most breathtaking tube in the world, by all measurements, at all levels. Like we always say at Soundlumia about these super rarities, 100% authentic to its true origin and 200% prestige of German tube brand. Now how about 300%? Siemens label + Telefunken Berlin kn6 Production (Siemens Hall 6) + ◇ Bottom = MEGA RARE! The "Crown Jewelry" ECC82 tube is here! If you've been seeking the reference vintage tube sound in the EC82/12AU7 land then look no further. Designed for high end amplifiers and preamplifiers, Telefunken ECC82 provides high level gain with ultra low noise and are unquestionably the most sought-after vintage tube and treasured by audio professionals and enthusiasts. Like any other Telefunken tubes, they 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.

Appearance & Cosmetic condition Beside the fantastic sound signature, we treasure this pair also because both tubes are in pristine cosmetic condition and the Berlin date codes on the side are visible on both tubes: k6n ⟂0 L (k6 = Siemens Hall 6 production, ⟂ = Telefunken Berlin, 0 = 1960 , L = December) k6n ⟂0 L (k6 = Siemens Hall 6 production, ⟂ = Telefunken Berlin, 0 = 1960 , L = December) And of course the diamond mark on bottom - the symbol of the best sound one can ever find on ECC82's.

Return Policy - Please READ carefully Returns are acceptable if we made a mistake by delivering you wrong or defective products. Tubes we sell are guaranteed to work because we run professional tests and sound evaluation TWICE: before they are approved for listing AND before we ship them to customers. So the "defective item" case doesn't exist and please do not bother trying - this type of returns will NOT be accepted without proof that tubes are faulty and we will open disputes with eBay. Sound experience is very subjective and we do NOT accept returns because you do not like the tube's sound signature or because you changed your mind about your purchase. Please contact us to work things out before submitting return requests claiming "item is defective" or "item not as described" or "just didn't like it" or "changed my mind." Tube rollers abusing the return system will be reported to eBay immediately and negative feedback will be left to your account - that's guaranteed. We have already opened several dispute cases to report abusive buyers and eBay has always ruled in our favor. International buyers who request return or refund claiming your country's import duties or sales tax/GST/VAT are too high will be reported to eBay immediately for dishonesty and will be permanently blacklisted from purchasing from Soundlumia. We are committed to working closely with eBay to help rid the marketplace of dishonest, unjust, unreasonable, abusive buyers that are detrimental to the vintage tubes market and the audiophile community.
