JJ ECC83S / 12AX7 Preamp Vacuum Tube
The JJ ECC83S / 12AX7 preamp tube is a fantastic performer at a very affordable price.
From our review of this tube: "The compact plate structure does nothing to dampen their sound or dynamic response. I find them to be well balanced. While not as harmonically rich as others I tested, they do provide high gain without the usual noise and microphonic problems you would expect. This is great sound for your dollar..."

JJ ECC83-S / 12AX7 | I really wanting to like JJ, but not getting the love back.
by Chris in SF
I notice JJ are very picky with any particular type of amp. They sound so brittle, noisy when plugged into my Fargen 1968 Super Lead clone. it produces an unusual, almost “electric hizz/buzz” noise when a note is played. Every single JJ-ECC83S I bought have that unusual noise I mentioned above.
As far as the overall tone, it does have that “chunky” low mids that I like, but that brittleness, noise above and the quick decay that is putting off.
JJ ECC83-S / 12AX7 | Put the sparkle back in a 50s era console.
by Christian Jennings
I replaced all the 12AX7 tubes in my Motorola Drexler console to JJ-ECC83S. Makes a big difference. The bottom end was very mush with the old tubes and the high notes were not very clear. I just put the new ones in and big improvement.
JJ ECC83-S / 12AX7 | применял в hi-fi
by Роман
Эта лампа была в усилителе,когда я его купил в сочетание с китайским 12аu7,что давало довольно гармоничный звук.Теплая,густая и приятная,гладкая,басовитая лампа.Конечно размер сцены и локализация инструментов не эталон,но так сказать,имеет изюминку,особенно в сочетании с чем-то ярким и динамичным.Для скромной цены очень хорошо!!
-----------------
This JJ-ECC83S tube was in the amplifier when I bought it in combination with the Chinese 12au7, which gave a rather harmonious sound. A warm, dense and pleasant, smooth, bassovaya lamp. Of course the size of the scene and the location of the instruments is not a standard, but so to say, has a highlight, especially in combination with something bright and dynamic. For a modest price very good !!
Best for the price

This tube came with the amplifier, from the fabric.
It is a good sounding HiFi tube. A little laid back,
in the highs, but still liquid and clear. Midd, and low end, is accurate and nice sounding.
It can not compete with my NOS tubes, but having
this low price, it is a good buy.
