The JJ ECC83-S tube has several improvements in its construction from the old ECC83 version.

From our review of this tube: "This tube sports a different plate design than found in most 12AX7's. When you look at them you can't help but think that they must be rugged and good for the musician on the road. 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. If you're using a combo amp and find the Philips a little rich sounding, the JJ ECC83 / 12AX7 may be your solution."

I replaced all the 12AX7 tubes in my Motorola Drexler console. 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.

I really wanting to like JJ, but not getting the love back.

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 ecc83-s 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.
