JJ ECC83 / 12AX7 Vacuum Tube
JJ ECC83 / 12AX7 Vacuum Tube is rated 3.625 out of 5 by 8.
Rated 2 out of 5 by from Good but flawedI tested these in a fairly revealing setup. Warm and musical but somewhat colored. There is a midband suckout of detail and air. They would work in a overly bright digital rig but I would not recommend them if you are looking for neutrality and transparency.

Rated 2 out of 5 by from No sir, didn't like it.This sounds pretty crappy. I've got 6 different 12ax7 tubes now and this was the worst of the bunch. Maybe I got a bad one but I prefer the WA and the LPS Sovteks.

Rated 5 out of 5 by from Fantastic TubesI ordered 6 12AX7s for my Boogie combo and they were shipped quickly and securely. I also saved a nice bit of money through Parts-Express. Tone-wise, they're new JJ tubes, I'm not going to get into their sound, if you're looking for durable, toneful tubes, you can't go wrong.One thing to note is that the glass nubbin on the top of tube is slightly longer than most Sovtek/Tung-Sol 12AX7s, so if you have a clamping tube system that comes into direct contact with the tip of the tube, it may be a bit more snug than you're comfortable with, but that shouldn't be an issue for most people.

Rated 4 out of 5 by from A bit noisy.Even with the spiral filament, some AC hum is heard. Hum was not nearly as noticable with the original tubes that these have replaced.

Rated 3 out of 5 by from JJ 12ax7Tubes seem to be testing low here lately for transconductance. Parts express does a great job of getting the product out and on time but I think JJ is slipping in quality control.
