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.

Ratings & Reviews
My favorite new production 12AX7
by Dana Hood
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.
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.
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.
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.
by some utter unknown
Very warm with enough gain for some great distortion. Just real smooth, balanced, mellow, bassy, but not overly bassy or too muted highs.
