    I was looking fora v1 tube to tame the highs and add some warmth to my Vox AC10 and the Tung-Sol 12AX7 seems to have gotten me much closer to that.

    Great in the first position of my Peavey Classic 30 along with the Sovtek 12ax7LPS in the 2nd. Fat clean tone, headroom and musical tone. The combination improved the sound of the amp.

    I've used every new production tube make in my many amps . The current TungSol 12ax7 is by far the best quality out there . The highs are clear and clean an the entire sound is transparent compared to a JJ . Yes , they're somewhat more expensive , but for V1/2 in a clean amp they are unbeatable , Tubedepot will provide every possible grading option too , which others don't .
    Matched sides for push-pull , low noise/micro for higher apps and vibration , plus high-gain for gas-heads . Well worth the cost .

    I installed a set of these in a Orange Dual Terror. The first thing I noticed was how dynamic they were. Soft picking or finger picking yielded a clean sound, as I dug in with a hard attack, the gain followed. They are nice and crisp, very articulate and loud. In comparison with the original jj tubes that came with the amp, the jj's yielded a fuzz type gain but almost no articulation. No matter how softly I would pick, it just wouldn't clean up. Could have been that the jj's were tired, dont know.
    I'd suggest these if you're looking to tame your terror, make it more articulate but retain the gain.

    Can't beat the Tung-Sol in just about any preamp position. I totally concur with this being the best of the best new manufactured tubes!

    Nice tube the sound is actually way better than the Ruby it replaced. Will get more of those in the future. ;)

    Worth the purchase! Bought 3 for a 1979 Marshall JMP 2203 (replaced JJ's) and loved the sound I was getting! Seem to make the presence of the guitar strings a bit more clear and much more gain than the tubes before. I highly recommend them!

    Great tube, running with GT in V1, JJ in V2, TS is in the driver's seat. Lovely warm yumminess.

    Like all of the guys mentioned in this review section, the Tung-Sol 12AX7 is the one to use in V1 position. Big warm sound, bright and overtones not to piercing. Just perfect for my tone buds! Go for it!

    I use the Tung-Sol12AX7's almost universally in V1 of my amps- everything from Mesa to Marshall Plexi and 2204 to Frnder Tweed/BF/SF amps. They make just about every amp sound nice and bright with rich overtones, without being piercing. Not great for a cathode follower position but fantastic for any preamp tone spot. Recommended if looking for a new production tube.

    Best-sounding new 12AX7 i've heard!!

    reviewed by: JP

    I use the Tung-Sol 12AX7 New Production Preamp Vacuum Tube in the V1, first pre-amp gain stage in two of my hand built tube amplifier designs - a 30W with 3 12AX7s and a 20W dual channel with one 12AX7. For the 30W design I tested Tung-Sol, a Mullard, and a JJ in all three tube positions. The Tung-Sol gave me the best results in V1.

    This tube has very low noise due to a spiral filament and short plate. The gain is low-to-moderate, the tonality is clear, uncolored, and stable. It is dynamic and has good headroom.

    This makes it an ideal choice for the first gain stage, where I use the amp's design for tone / gain shaping.
