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.

    best preamp tubes ever.

    This tube was placed on the V2 of an H&K tubemeister 18. In V1 was placed a Tung-Sol 12AX7 New Production. The tubemeister got much better with much more functional tone control. Highly Recommended

    I purchased this tube in addition to other tubes to replace the old tubes in a Vox Cambridge Reverb amplifier. I was impressed with the sound and reliability with these tubes.

    I ordered this JJ-ECC83 to mate with a J-6V6. This preamp solved all my problems. Good price, fast delivery.

    I ordered just one tube for use in my DSL40C. I was searching for something similar to the my amp's stock tube. This tube has identical construction and tone. I like it and sounded well.

    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.

    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.

    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.
