JJ ECC82 / 12AU7 | Использовал в hi-fi в качестве драйвера


Использовал в hi-fi,звучание теплое и гладкое с большим,но не очень структурным басом,мягкими не сильно выделяющимися высокими частотами.Сцена по размерам скромная.Слушать приятно.
Used JJ-ECC82 in hi-fi, the sound is warm and smooth with a large, but not very structured bass, soft, not very prominent high frequencies. The scene is modest in size. It's nice to listen.

JJ 12AU7 A fine tube!!


As far as current production tubes versus NOS, this tube really stands up to the TELEFUNKEN 12AU7/ECC82 easily when it comes to the smooth transitions and being quiet concerning thermonics (Tube noise). For the price, I do strongly recommend this tube! I've had a pair in my HH Scott since 1997. As for being the best....??? I do love this tube...I'll just happily keep my Telefunkens in their box.

Very, very nice hi-fi tube!


I find the biggest difference in sound when rolling tubes in my Icon Stereo20 PP integrated amp is realized when changing out the pair of ECC82 phase-splitters. So far I have tried the stock Shuguang, Electro-Harmonix (see my review of this FINE tube on this site), and this JJ. The JJ is probably the best all around tube of the bunch. Nice, smooth midrange, but not too buttery. A very balanced tube, with brilliant, airy treble, that just avoids being too harsh. I switch between these and the EH tubes, depending on my mood. Too bad I have yet to find a tube that combines the best qualities of each in a single valve! Now THAT would be some valve!
