Compared to the New Sensor Corp. Svetlana which has a rather strident midrange, the new Mullard EL34 has been considerably smoothed. The overall sound is more balanced and very warm. This is great news for people with something like a Marshall since they are inherently midrangey. The low mids are nicely balanced to prevent any boomy tone.
If you are curious about how these fare in a hifi stereo amplifier be sure to read the Wall of Sound EL34 tube comparison for details.
This new production EL34 tube is New Sensor's reissue of the famous Mullard EL34.

Ratings & Reviews
Mud Machine. I guess if you play rock and blues, this tube is ok, but I play clean blues/jazz/R&B, and this tube is absolutely terrible for that. Low mids are muddy as hell.
Mullard EL34 sound and burn-in
by David -
I recently needed to replace the EL34 output tubes for my mono-blocs, (six per channel). The sound of the amps is fantastic, with a great sense of realism. At first I tried to buy just two used tubes off CAM, but I was unsuccessful. So I went ahead and bought twelve matched EL34s from The Tube Store. For the first several hours of listening, the sound was ok, but the sound stage was smaller and congested. At 20 hours the mid's sounded like honey poured all over them, (not in a good way). Finally at 30 hours the sound opened up. The emotion of the musicians, and the timbre and spacing of the instruments came back. Now, at 50 hours my records sound better than ever. Not sure if the sound will continue to open up, but I suspect it will. I can highly recommend the Russian Mullard EL34s. Thanks also to the staff at The Tube Store. Super knowledgeable and informative!
Marshall + Mullard = Melodious
by Joseph Weldinger -
I purchased a matched pair of these along with a matched and balanced quad set of Mullard CV4004/12AX7 tubes for my Marshall JCM602 combo, and after slightly adjusting the bias back to the referenced -42V I am very pleased. The clean channel sounds much better, i.e. the bass response is punchy and tight while the mids are well balanced, and the highs are sharp and crisp. In relation to Marshall VLVE-00010 (Svetlana EL34) or Marshall VLVE-00042 (Shu Guang EL34B), the overdrive channel does lose just a tad of that trademark Marshall tone to my ears, but overall I consider the tradeoff to be well worth it.
I was disappointed in this tube. I honestly thought based on what I have read about it that it'd be a great product in my guitar amps. I use only Marshall 100 and 50w amps, not sure this has any bearing, but I tried it in both 800 series amps, and the newer JVM. Both times experimenting at differing bias points it just didn't deliver the goods. It was a good, stable tube that biased up quickly and remained steady at a specific bias point without drifting, however it just seemed to lack character. Boring is the most accurate, simple word I could use to describe it's performance. Other tubes in it's price range and cheaper just blow it away.
My choice el34
Nothing for me not to like. They are quiet operation and biased just fine in my prs hxda 30 head. Thetubestore does a great job on matching.
I've only used these in a marshall style amplifier and they are my go to for that. They sound wonderful pushed with a thick tone but controlled bass without exaggerated highs, smooth overall. Good sustain.
For guitar amps, it's a great choice.
