JJ-ECC83
These tubes are immediately discernible from other 12AX7. They have a construction that is similar to a frame-grid tube - similar to the Telefunken ECC803s. This construction makes them very rugged and reliable. This is one of the best new 12AX7 for any guitar amp. It is very musical - rich with great harmonics. An excellent tube in all Marshall amps in the three preamp positions.

I use this tube as my everyday listening tube currently. I favored it immediately above new production Tung-sol which came with my Jolida Tube Dac III (I have 2 of them, which allows me to A/B them). There was more harmonic information and slightly more warmth, but plenty of crisp high frequency detail and air. It is a very coherent sounding tube that faithfully plays back music with a sense of the whole recording; it doesn’t try to dissect the recording, while still allowing one to follow individual aspects of a performance if desired. It gives you that bit of “extra” that solid-state always seems to lack on stringed instruments, voices, timbral resolution, etc. It is subtle but noticeable, which will please those who don’t want to veer into tubby rolled-off sounds. Compared to a new production Mullard, it is a little less boisterous, in terms of its presentation. The Mullard gives a little extra “extra”, relative to my comments above. However, while the Mullard is slightly preferable with classical, jazz, small ensembles and acoustic performances due to its highlighting capabilities, one might argue it is a bit less refined and coherent, especially when pushed hard. This isn’t bad, just different. Even certain metal tunes can sound great with the Mullard, but it sometimes loses its composure. So then, the JJ ECC83s, is a stellar all-rounder and a very satisfying tube. Highly recommended!!

Whether you are looking for good performance or low price, I can recommend the JJ 12AX7. I have it in a number of guitar amps (some that I built) and a hi-fi amp (that I rebuilt) and they work well in both applications.

The JJs are my go-to tubes for my AC15. They're rugged and inexpensive, and they are well-balanced with breakup at fairly low volume.

Used these as a replacement for the original Miniwatt tubes in a Kriesler 11-95 radiogram from the 70's. Excellent bang for your buck. Work as expected. Would highly recommend.

The JJ ecc83s is a excellent preamp tube! In the modern times we live in it is great to be able to purchase a new tube of this quality. I tube rolled nos mullards, rca, ge, and compared them by ear then by recordings all at the same settings, and my conclusion is that the ge is quite close to the jj but not as open and airey, the mullard is good like the rca, but with my setup the jj is hands on a better tube especially because of availability and price! I use them in all my amps, and to my ear is better than the reissue tung sol. Of course there are a lot of factors involved in acheiving that sound guitarists are looking for. For the price, buy one or two break them in 20+ hours and give them a go. I've been using jj tubes for the past 6 years, have always bought them from Tube Depot. They are the best tube supplier that I've ever ordered from, so do your ears a favor and listen to the sweet harmonics you can get from the JJ ECC83S!

Like their 12AT7, this is really sturdy and low in noise. I really like it in the V4 slot in my deluxe Reverb.

I decided to replace the 3 12AX7s and 2 EL84s in my Crate VC20 amp because one of the tubes had gone microphonic--I didn't know which one, so I decided to replace them all. I used three of these JJ tubes because they were reasonably priced and had very good reviews. I'm very happy with the way the amp sounds with these tubes (plus two new JJ EL84s) and it fixed the microphonics problem I was having. No complaints.

I've solved many problems with vintage and new combo amps with these tubes. Can you get a better tone? Sure, but realize expensive NOS tubes have been picked over for decades, and even mil spec or hospital grade tubes from yesteryear, while unique and sought after, often ring or squeal in a combo amp. The JJ ECC83s is very quiet and well behaved due to robust design, and sound so good at the price point, that it is a no-brainer. Tube Depot's extensive testing and the volume of these they deal with can get you very close to vintage tone with no worries!

5stars Good solid tube if your on the cheap budget build. You can't go wrong. Make sure you stay at or below the stated ratings. In other words don't blast this tube with high plate volts. It will last for decades. .

This is a terrific value tube for most duties . Robust and long lasting . Not as articulate as TungSol , but not as unreliable either. Rolled treble is good for bright amps or even slightly hissy resistor noise reduction .

I use JJ 12AX7 tubes extensively in new builds. Some amps get three of these, and in some amps I use this tube as a phase splitter. They're also resistant to microphonic. They're a great value.

Have used JJ power tubes, but this is my first JJ 12AX7. I used it on a 2-stage external gain boost, with a B+ of about 230VDC. Lots of nice harmonics, PLENTY of gain. I compared it with a NOS GE 12AX7, and yes, there was a little, difference, but not enough to notice or care. With Tube Depot's incredible price, this will now be my 12AX7 go to.

One of the Sovtek 12AX7s in my Peavey Classic 30 blew. Since the other two preamp tubes are the same age, I decided to replace them all with the JJECC83s tubes-I absolutely love the sound. First time using Tube Depot, very pleased with the service. Ordered around 10:00 pm on a Monday, received my order Thursday afternoon. I will definitely use them again for future amp related needs.

Ordered these tubes as part of a kit for my Blues Jr. Instant improvement in the sound of the amp. Tubes shipped the same day I ordered them and arrived very quickly and well packed. I really appreciate that Tube Depot put these together in kit form so I didn't even have to think about what to order.I couldn't be more pleased.

I have a hand-wired JTM45 that had a bad hum (even on standby.) It also had a high noise floor when on. I ordered a set of these with the low noise and matching options. It fixed the problem 100%. The amp sounds amazing and smooth and it's quiet as a mouse. I don't see how you could go wrong with these. Shipped fast and packed really well too!
