If you've been seeking the reference tube sound then look no further. Designed for high end amplifiers and preamplifiers, Telefunken ECC82 tubes provide high level gain with ultra low noise. And are unquestionably the vintage tubes sought after and treasured most by audio professionals and enthusiasts. 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.

Professional testing & sound evaluation. Both tubes tested Strong NOS (110%+ nominal mutual conductance) on a Mercury 2000 tube tester with the following result mutual conductance in. Tube 1: 3,200/3,200.

Tube 2: 3,180/3,300. 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. The pair worked wonderfully & sounded terrific in our test amp (Woo Audio WA7e Fireflies) during professional sound evaluation.
