Please see our article on 12AX7's. https://www.amplifiedparts.com/tech_corner/12ax7_comparison_of_current_made_tubes It will rate tubes by gain and noise.

Some people will match a preamp tube and this is what is typically referred to a "balanced." We do not offer this service. Most of the time is is unnecessary.

Hi, all 12Ax7's are comparable with each other. This will work just fine.

The Tung Sol is a very warm and creamy 12AX7 with nice detail. We would suspect that you would get these attributes with the Vox.

Both of these Tung Sol 12AX7's are ECC803S. They are very close but the gold pin will have slightly less gain in the mids. The ECC83 is a mid gain tube and will have less gain than a 12AX7 (ECC803S).

Absolutely. High gain preamp tubes combined with low numbered power tubes should provide your amp with earlier access to breakup.

Bought a few of these and love them but unfortunately they have developed bad rattle to them. Switched them out with some good ol' JJ 12AX7 and rattle disappeared. Maybe just a couple bad apples in the batch but think I'm going to stick with the JJs.

Installed these tubes in blues jr Iii along with cannibus Rex speaker. It has increased headroom better dynamics and got rid of thin brittle highs. Everyone I play with noticed right away and could not believe the difference. Will do same mods to my USA bjr and run them both with Aby box.been chasing tone for a long time and finally got what I wanted.

I really like these tubes... I like these as a high gain 12AX7.... they are big and loud when played, yet nice and quiet at idle. Comparing a few things, the China 12AX7's have the gain, but with an annoying hiss added.... The JJ short plate is quiet at idle, but not as much gain. If I'm going for strong gain, I pick the TungSol... if I want modest gain, I pick the JJ. I really hate amps that don't shush when they aren't being played...

I replaced my JJ's with these in my Bugera 1960 Infinium and wow what a difference. I also put in tungsol kt66's which i also love. I decided on the full tungsol set after chatting with the online support. I highly recommend these tubes and talking with their support.

I replaced a set of jjs with these in a fender champion 600 (reissue) and man, what a difference! much smoother than jjs. I found the jjs so crunchy that they came off as harsh. the tung-sols are a great alternative that I'm probably going to stick with!

plus amplifiedparts.com has always been great to deal with!

I used the Tungsol to replace the stock GT tubes in the preamp section. What a difference! These are much quieter. I lost the hiss tube noise.The clarity is better and tone more balanced. Not as harsh as the GT's Also not as bright yet still plenty bright. The amp sound much better. Note. I replaced three tubes: the V1 normal, theV2 vibrato and the V4 Reverb recovery/ half gain stage for vibrato channel.

Got a Bogner Alchemist amp head and it was lacking something in the sound decided to put these babys in for preamp 5 straight across and lets just say I completed the task with 6L6,s in the power section and let me tell you night and day sound Im totally sold on them my amp took on a whole new sound its butter.....Dave

I've replaced a Chinese 12AX7 with this.
-Becoming quiet actually. It does NOT mean no noise, but feel like divided sounds from noises so each tone is more clearly.
-Getting smooth and depth in both low and high ends. With rich musical tone in CLEAN sound, I've fun to "roll-off" control with volume and tone knobs.

So, this tube would make me a touch sensitive player. RIP Cornell Dupree...

This is a good 12ax7. I found when comparing it to the JJ12ax7/Ecc83 it didn't push as hard. The JJ seems to be pure power, the TungSol does not. I think the TungSol is more musical and more tonally balanced overall than the JJ, better for cleans but not for overdrive especially when using the Tungsol with a 6l6.
