I have a few of these and im using them in my various amps. These reissue Tung-sol tubes from New sensor are easily, IMHO, one of he 3 best new production preamp tubes being made. For years I have used original U.S.A made Tung sol tubes and these are genuinely close enough that i use them inter-changeably. This has the sound of the american 12AX7: powerful, fully equal output-range of lows mids and highs, and great OD distortion, just slightly looser than Brittish Mullards or German Telefunken. BTW The other 2 excellent new prodcution tubes are the JJ ECC803 long plate, and the Mullard 12AX7 reissue. The Mullard sounds awsome but is a bit fragile, can become microphonic with a lot or rough handling.

No Warning About Cathode Follower/Phase Inverter Use

I purchased three of these when I was looking to re-tube my Peavey. The item's description does not state that these can not be used in a Cathode Follower or a Phase Inverter position. Fortunately, I found out about it before replacing the tubes. I contacted "Otto" through Tung-Sol's website who confirmed that these can not be used in those positions. It would have been nice to have that information clearly available before I purchased 3 of them. So, after purchasing a Sovtek 12AX7WB to use in the Phase Inverter and tube rolling from other amps, I was able to spread the Tung-Sol's around. To be quite honest, I find the tone change negligible. I've rolled the Tung-Sol's, JJ's and Ruby 7025SS's through a variety of positions on a variety of amps and can't hear enough of a difference to say that they are wonderful or bad.

Buy this tube!

By Chris

from tucson az

Comments about Tung-Sol 12AX7 Tube:

Put one in my Rocktron Gainiac 2, changed from night to day. The clean is crystal clear with that nice rich bottom end and the tube added punch to my gain, wasn't expecting that. Because of how great the microphonics are in this tube I could back off my noise gate. All in all I would say buy this tube throw the old one in the trash and move on!!!

These Tubes are great...

By Lee Olsen

from Cary, NC

Comments about Tung-Sol 12AX7 Tube:

I bought an ART DPS II recently and changed the 12ax7 tube out on what I have heard from several people who have owned the unit. I must say I am very pleased with these tubes so far. The Art DPS II came with an Electro-Harmonix tube which I wasnt too crazy about when plugging in for the first time. I was messing around with the settings/gain etc and couldnt find the sweet spot. It sounded a little off. I questioned why I bought the unit in the first place based ion these great reviews. Well I decided to give it another chance and change out the tube and low and behold I was very impressed immediately. I have a Presonus Firestudio Project which the preamps sound a bit harsh in my opinion. I know have 2 extra inputs via spdif and so far I am very happy with tube purchase.

Tungsol 12AX7 awesome !

By Ecurb

from Panama City Beach, FL

Comments about Tung-Sol 12AX7 Tube:

First off, let me tell you about the gears I use. 1) Guitar - PRS Tremonti SE 2) Strings - Ernie Ball super slinky 3) Amp- Used Marshall valvestate 65-watt 4) Digitech Screaming Blues overdrive pedal Not happy with the stock tube (12AX7, Made in Yugoslavia) that came with the amp, I've replaced it with this one-Tungsol. What a big difference in tone ! It's got more gain, clarity and better sustain. It's quiet also and the sound of my amp, either clean or distorted is more pronounce and sounds just more musical now. Those people that wrote the same good reviews here and anywhere else are not mistaken. Get this one if you want to sound good but on a budget, this is the tube for you !

Excellent Product

By GEOFFREY BRANTNER

from LA

Comments about Tung-Sol 12AX7 Tube:

Replaced the original tubes in my VHT Special 6 Ultra with two of these. The amp in now less noisy, and maybe sounds a bit warmer. On another note, I did not like the way they were packaged by the GC staff. They were put in the bottom of a small box, and then enough shipping paper to wrap them in was simply squished in on top of them. They could have easily taken the extra 5-seconds to wrap the tubes in the paper, but thankfully they arrived intact. I sent the GC customer service address an email about the packaging and have received no reply.

Tungsol 12ax7 Tubes

By Cliff Hughes

from Miami,OK

Comments about Tung-Sol 12AX7 Tube:

I replaced the stock Fender tubes in my Fender Super Champ XD amp with this tube, and I was impressed. I had experimented at first with Ruby power tubes with it. Then I tried some JJ power tubes with the JJ preamp tube. I came back to the Tungsol 12ax7. To my ear I liked the tone better. I had also put an Eminence Rajin Cajun 10" speaker in which blew away the stock Fender speaker. I aslo had much more volume! So for now it's JJ 6v6 matched power tubes, Tungsol 12ax7 Preamp tube, and Eminence Ragin Cajun 10" speaker. I get a great big sound now, and my bandmates love the sound also. I bought a set for my Fender Twin Reverb also.

Tungsol never disappoints

By Mike Sarro

from Manchester, NH

Comments about Tung-Sol 12AX7 Tube:

I have used other major brands of Ax7 Preamp tubes which are of similar quality but just lack the tonal characteristics of the Tungsol's. I have a business associate the repairs and rebuilds amps and he always praised them so I finally tried them last year and it is now my preamp tube of choice. I recently purchased a Tweaker 15 (great little amp by the way) and it lacked some character and I know it isn't the amp. I changed all 3 V1, V2 and V3 (balanced AX7) and what a difference. Whatever it lacked in tone mostly highs came right back. They are known for their 6V6 Power Tubes as well.

Better than JJ's

By Rob

from Bel Air MD

See all my reviews

Comments about Tung-Sol 12AX7 Tube:

I have a Marshall JCM 2000 TSL 100. I was looking to replace by preamp tubes. I have looked around and one of the sites for tubes said to use Tung sol with C Wing powertubes. I gave it a shot and purchase 4 Tung Sol tubes. I soon as I played I notice a big diference in my sound. more like the brown sound that a Marshall is know for. I would recommend this product to everyone. A step up from JJ tubes and you can take that to the bank!!!

Does The Job

By Michael Brozovic

from San Diego, CA via Detroit, MI

Comments about Tung-Sol 12AX7 Tube:

Replaced the V1 preamp JJ tube in my Orange Dark Terror with this Tung-Sol. It definitely brightend things up quite a bit without being shrill, while also adding some nice bottom end without any muddiness. This tube gives me more tonal control over my Dark Terror which I play though an Orange PPC212 Open Back cab.

        I installed these in a Hughes & Kettner Tubemeister 18. The original tubes were a little bit too clean sounding. The amp has much more overdrive now and it's a smooth overdrive, not nasty high end screech like some other preamp tubes. I have some vintage NOS RCA tubes on order but these work well.

        Installing (2) Tung-Sol 12AX7 Tube

        By OLIVER JOTOJOT

        from Pittsburg, CA

        Comments about Tung-Sol 12AX7 Tube:

        Using a microphone pre-amp on the stereo mix out of a Mackie LM-3204 Stereo Line Mixer, I had to replace one tube in an ART Dual MP. Installing (2) Tung-Sol 12AX7 Tubes made it an affordable replacement. The sound is fuller and clear on the contours of the low ends. Tip: Remove (pulling out) and install (pushing in) the tubes in a gentle, circular motion.

        When considering the small price of admission, these are the very best IMO. If money were no object, I would still use these preamp tubes.

        Comments about Tung-Sol 12AX7 Tube:

        This tube is to replace the one in my Presonus preamp, it went out. I use the preamp for recording acoustic guitar and vocals. This tube sounds great! Awesome!.. If you want clarity and tight clean sound. This is the tube to invest for your preamp. If you want clarity, use this tube, good shielded balanced or mono cables, a direct box, a good mic for recording vocals, acoustics, or electric guitar amp. If you hear a hum or buzz sound, it means something is not making a good connection or frequency waves releasing from TV or some type of high power equipment is catching on your cables, mics or pick ups. Use good shielded cables. This tube is a good investment to start.. I give it thumbs up!

        Great tonal improvement

        from undisclosed

        Verified Buyer

        Comments about Tung-Sol 12AX7 Tube:

        My ENGL Powerball v1 was in desperate need of re-tubing in the preamp section. I put 3 of these in along with an 12AT7 in the phase inverter (12AX7 in the pi slot was a bit too harsh sounding), and BAM! Crystal clarity, nice breakup, great tonal distortion and tight definition and punch. These Tung-Sols are great for improving and maintaining that high gain, high octane metal sound.
