Perfect balanced vintage Lorenz ECC82/12AU7 Audio Tubes - Made in Germany 1960s - Near NOS - Super Rare

Tube Summary

These must be the most exotic European audio tubes! So elusive they're even unheard of in many parts of the world. Not many of these tubes are around, either, let alone a strong matched pair! Although lesser known than big names like Telefunken and Siemens, they are just as remarkable as any other German-made tubes and have been the go-to tubes for guitar amplifier users. 

Sound Qualities

Like most German tubes, they are characterized by an impressive open "air" at the top end, and the soundstage is large, even in mono applications such as my classical vinyl records from the early '50s, these tubes  provides you with a full 3-D imaging. The midrange is ruler flat,  a.k.a. natural sound, and the bass is tight and accurate. One very unique feature of Lorenz tubes is the fine sense of dynamics you get from anything you play - it feels you are enveloped by an invisible "musical body" that you can't escape from and it's cerebrally joyful. Last but certainly not the least, as the legend goes for all the German tubes, these are astonishingly quiet. If you're seeking European ECC82/12AU7 tubes with ultra low noise look no further. These will get the job done fantastically.

Appearance and cosmetic condition

Besides its wonderful sound characteristics, we treasure this pair also because its great cosmetic condition as well. 100% of the paint is still intact, including the Lorenz logo and ECC82 lettering.

Our full tube sound review was written 100% based on the actual listening experience while this tube was running in the system described above.

Professional Tube Testing

The tube tested Near NOS (90%+ nominal mutual conductance) and perfectly balanced on a Mercury 2000 tube tester with the following result (mutual conductance in both uMhos and percentage of nominal):

2,800/2,950 (93%/98%)

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 tube's ability to amplify sound, so the higher these numbers the stronger. No short, leakage or gas.
