JJ E83CC / 12AX7 Preamp Vacuum Tube
The new JJ E83CC (12AX7) vacuum tube is here! It is modeled after the legendary Tesla/Teslovak E83CC preamp tube using a frame grid internally.
From our review: "The tube sounds very good and it’s extremely quiet. Spiral filament winding does seem to have an effect. The noise floor is better than the standard ECC83S. Frequency response is excellent. In the lower register of guitar it produces a nice thump. Great for palm muting, drop tunings and percussive rhythm. Mids are upfront but not honkey and there’s no issue with highs. When I slammed the front end of my amp with a boost pedal the overdrive was quite musical and focused. I didn’t get heavy mush. I also ran a pair of these tubes in my phono stage with good results. I’d have no problem recommending for use in studio rack gear or other audio applications."

JJ E83CC / 12AX7 | A great all around 12AX7 / ECC83!
by Steve -
I got a pair of these JJ-E83CC yesterday to find out what they could do in guitar amps, and I was impressed.
A Blackface Fender Showman and a mid 70's Traynor YBA-1 were the amps used to try them out. For comparison, I used a selection of 12AX7 types ranging from Shuguang 12AX7B to Telefunken ECC83.
Measuring the voltages and gain in the Traynor ( V1 socket ), both the JJ E83CC's biased perfectly ( about 2/3 of B+ ) and well matched, both tube to tube and section to section. The gain was just as well matched.
JJ ECC83's showed a bit more internal tube noise, the Telefunken a bit less.
The real good surprise came from checking the mechanical noise / microphonics. With either amp gain set to full, the JJ E83CC's were the quietest of the tubes I tried.
If you're looking for a 12AX7 type tube that has good gain, great matching between sections and from tube to tube, along with low noise / microphonics, the JJ E83CC could be the one for you.
