From our review: "I find the Svetlana 12AX7 tube to sound a bit smoother than the 12AX7EH and it has less gain than the Tungsol 12AX7 tube. If you are not inspired by the Electro Harmonix and also find the Tungsol too grainy then this is the 12AX7 tube you want to give a chance. It has everything you want in a good pre-amp. Low noise, no microphonics issues, and very clear and open without being too bright."
This new production tube is manufactured at the New Sensor Corp. owned Xpo-Pul factory (also known as Reflektor) in Saratov, Russia. Use it to replace all other 12AX7, ECC83, and 7025 tube types. Solid construction and build quality and all test great on our equipment.
Not to be confused with the older Winged "C" version, this one is of far better quality.
One other note about the construction of these tubes is they have filaments that are almost completely encased in the plate structure. They don't "light up" brightly when working properly.
Lot better than expected and very Lo noise .
They sound beautifully with rich harmonics.
More than satisfied.

I really like this tube. I was running the Tungsul but felt they were too harsh and kind of dull. I tried one of these tubes in V1 in front of the Tungsol in an '82 Fender Champ II. I was pleasantly surprised! Now I'm curious how it would sound with two of these. I'm still finding great sounds with the only the knobs so it may be a while. If you are looking to try something different try this tube.

What a surprise. Its got power, touch sensitive, bright when needed. Got in my Vox ac4tv with a nos tungsram el84. Chords beautifully. Lead notes are touch and go. Its like I'm using a sustain pedal, but not overly. Clean and powerful, not messy with the nos power tube. It crunches clean. Very different 12ax7. With reissue power tube I don't know. I will buy more of these. I thought I needed a new speaker. I got a new amp for 71 bucks. Nos power tube, Svetlana 12ax7. I'm hyped. Playing is easy again. Speaker maybe later

I roll a lot of tubes in a number of boutique/higher-end amps (Diezel, Bogner, etc). Recently I'd experimented with getting clarity, articulation and punch without sacrificing sizzle in a couple of my notorious high-gainers. These worked wonders; and so much so that I ported a few over to the tone stacks of my otherwise GL-ECC83 loaded amps with equal satisfaction.
Warm, clear, and smooth but still giving great growl and focus - terrific tubes, awesome price, very quiet... Super glad I took the leap. Buying more this week!!
Lastly - Jon and crew are just above and beyond in the customer service and satisfaction department. Terrific guys who know their stuff and ship lightning quick!! My go-to place for literally "all" my tube needs. Thanks guys!!

A real gem
I've had my TH30 since they came out and have used Tung Sols almost the whole time, but there was always a harsh, unforgiving nature to the high end.
I put a couple of Svetlanas in it on a whim and was immediately gobsmacked. Gone is the harshness. Still tons of gain, but with a new warmth to it. The clean channel sounds incredible. Well defined bass and mids, lots of chime. Exactly what my ears have been wanting to hear. IMHO, Svetlanas are the best reissues out there.

Very warm with enough gain for some great distortion. Just real smooth, balanced, mellow, bassy, but not overly bassy or too muted highs.

Warm Svetlana 12AX7
I replaced the 4 12ax7's in my Crate TV120,
it always had a harsh loud sound to it.
The Svetlana's made it sound better then when it was new with a nice Warm
I can also get a nice crunch with it too.
I also tried them in my Traynor YGL1
(a 15 watt class A running 2 12AX7 and 2 EL84's)
The Svetlana's were as little bit to soft and I lost a bit of the Chime.
The Tube Store description was right on for the Svetlana's.
The Matched Sections Service makes a big difference too.
Great service from The Tube Store, got my tubes in 3 Days via Express Post.

Terrific in Fender 68 Custom Deluxe Reverb
This is the third set of 12AX7 in V1, V2 of my amp.
The stock GT branded JJs were decent when driven, but a bit dull when clean. Up next were Tung Sols, which were beautiful clean and just on the verge of breakup, but grainy and harsh when really driven.
The Svetlana hits the best of those 2, and then some. The description is bang on - clear and open, not too bright. They have a beautiful warmth when driven, and can be driven both smooth and with punch.

Great new production 12AX7
I never write reviews, but I am really impressed with this tube in a blackface Fender Bassman Head. It is quiet and sounds great. Hopefully it will last. Try it, you just might like it. Oh- I'm ordering more.

My favorite new production 12AX7
This tube's got a great balance of everything you want in a tube, and at an amazing price. I'm loving it in all three positions of my Vox AC15HW1X. It easily has more character and dimension than JJ. Compared to the New Sensor Tung-Sol or EH, or the Preferred Series 7025, its lows are more solid and defined, mids are richer, and highs are smoother but still clear and present. Breakup is very smooth and natural. It actually compares quite favorably with a vintage Tungsram (although the Tungsram is still just that much sweeter). This tube's a real sleeper, but I'd say it's the best new production tube I've tried.

Very musical mids. Big but tight bass response. Very smooth highs. Will take all harshness from your amp. More gain than a Mullard and just a little less than a Tungsol. Great in all positions. Perfect to tame a Marshall. Amazing for Classic to Hard rock
By Denny L. from Parker, CO
For hifi preamp use I find these tubes far smoother, refined and less bright than the EH, TS or JJ's...a real sleeper. By the way, I ordered on Tuesday and received my order on Thursday with standard shipping. Great service TheTubeStore!

I have built a Vibro Champ, but the gain of TungSol 12AX7 in the preamp was way too high, causing immediate distortion at almost all levels. I tried an EH 12AY7 which was ok, but the gain was too low and there was a bad interaction with the tremolo circuit. You couldn't hear the tremolo very well. The EH 5751 gold was much better. I was very surprised with the Svetlana. The gain was just enough not to cause severe distortion,especially at lower levels it is very clean, and the sound is as described in the review, open but not to bright. I also have nice mids and until now no microphonics or noise. The Svetlana 12AX7 together with the TungSol 6V6GT is for me a perfect match in the Vibro Champ.

Bought 5 of the Svetlana 12AX7s. One went microphonic in 100 days. The noise levels of two others became so high, they were basically unusable. The remaining 2 are reminders to avoid these in the future.
