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!
