Perfect matched & balanced pair of vintage Telefunken ECC82/12AU7 Audio Tubes - Smooth Plates - Berlin 1955 - Strong NOS - Extremely Rare
Product Summary
The "Crown Jewelry" ECC82 tube is here! If you've been seeking the reference tube sound 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.
Sound Qualities
Like any other Telefunken tubes, these ECC82's 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.
Professional Sound Evaluation
The pair worked wonderfully and sounded terrific in our professional studio setup for monitoring.
- Input: Cambridge Audio CXC V2 dedicated CD transport + Schiit Audio Bifrost 2 Multibit DAC
- Amplification: Woo Audio WA7 Fireflies (3rd gen) Balanced Headphone Amplifier
- Output: Focal Clear MG Pro open-back headphones
Our full tube sound review was written 100% based on the actual listening experience while this pair of tubes were running in the system described above.
Professional Tube Testing
NO shorts, leakage or gas. NO noise or microphonics.
Both tubes tested NOS (100%+ nominal mutual conductance) and closely matched on a reliable and recently calibrated Mercury 2000 tube tester with the following results (mutual conductance in both uMhos and percentage of nominal):
Tube 1: 3,020/3,080 (101%/103%)
Tube 2: 3,200/3,150 (106%/105%)
Good tubes start at 2000 and new tubes (incl. NOS/NIB) 3,000 - 3,100, and the Mercury 2000's rated mutual conductance (nominal) for new tubes is 3,000. Test result can also be seen in the pictures. In case you wonder what all these numbers mean to your sound experience, it's actually quite straightforward: mutual conductance directly translates to a tube's ability to amplify sound, so the higher these numbers the stronger. No short, leakage or gas.
Appearance & Cosmetic condition
Beside the fantastic sound signature, we treasure this pair also because both tubes are in great cosmetic condition and the identical Berlin date code is visible on both tubes although a bit fainted on one tube.
B aq 01 (B = Berlin, aq = 1955, 01 = internal batch number)
And of course the diamond mark on bottom - the symbol of the best sound one can ever find on ECC82's.
