Sonics
The long plate D-foil ECC82 tubes are considered as the best of the best; “they bring the concerthal to your room”; delivers an open holographic sound stage with transparency and detail. I refer to the many threads on the web for more information. Excellent preamp valve, low noise, very smooth extended highs, very good for all HiFi applications. Balanced and smooth sounding, recommended!
Test method & results
The tubes have been tested carefully with the official Telefunken test set-up and our sophisticated test equipment. Please read our testmethod for the ECC82 tube family. The measurement data below show that both tubes are matched and balanced. And fulfill the factory specs of a new/NOS tube.
