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.

    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.

    Purchased per Soldano’s recommendation for a Decatone amplifier. Completely happy with them. Tube Depot is great, and my purchase could not have gone better.

    I bought these for a fisher x100. It had a mix of vintage tubes in it including a legendary telefunken 12ax7. I'm quite happy with these Jjs as replacements for my well worn tubes.

    This is a great sounding tube in every position of my Marshall dsl. I tried it in my H&K Tubemeister 36 also. The price is excellent for the quality. I’m getting these for the H&K now also.

    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 .

    These JJ 12ax7 tubes are the only preamp tubes I have bought in a few years. No complaints. Have served me well and the price is lower than other brands !

    Completely re-tubed the tired old Super Reverb used all JJ's - what a personality change. Lower lows, crisp clean highs and so much in the between.
    YAY!

    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.

    Great preamp tube. I use them on all of my heads and consistent and reliable.

    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.

    Great tubes, used in vox AC-30 and they sound great.

    This tube sounds great in the cathode follower position of my 5f6a inspired build.

    Inexpensive and well made tubes. I used these in my Fender Blues Jr amp with great results. I will continue to use these in my other amps when needed.

    Great for the price. brought my amp back to life, I plan to get more in the future.

    These tubes are the best bang for the buck! Low microphonics and rattling! A little darker than other tubes but nothing EQ changes can't fix!

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

    I use this tube every gear on my head amps, It' very clear sound and natural.

    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!

    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.
