Mullard EL34 Power Vacuum Tube (Matched)
Need matched power tubes? Don't worry! Price includes matching in any quantity you need for no extra charge. Need a matched pair? Just order "2" tubes. For a matched quad order "4" tubes. Matched sextets and octets are available as well.The Mullard name and trademark have been acquired by the New Sensor Corporation. This new production Mullard EL34 vacuum tube is manufactured at their Xpo-Pul factory (also known as Reflektor) in Saratov, Russia. New Sensor is an American corporation and since taking ownership of this factory has been steadily improving the quality of current production tubes.
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.

Mullard EL34 | Affordable tube with good sound
by southerntubeman
A decent EL34 tube and affordable, however lifespan seems iffy, had one go bad at 7 months. Otherwise decent sounding tubes, a bit lacking the dimensionality of real XF2 British Mullards. My XF2's are 60+ years old. Apparently no one has quite matched the originals!
Mullard EL34 | Not as expected
by Adrian R
Purchased this MU-EL34 tube from the tube store approximately a year ago. The tubes arrived quickly and in perfect condition. I placed them in a Marshall JCM 800 50w amp, and biased around 35-36mA per tube. It biased up quickly and remained steady with virtually no drift in it's initial 8hrs of life. Tone is balanced with moderate power and headroom. Overall for me the tone was bland, nothing exciting to write about, just kind of boring in which from a 50w 2204 is rare. I then tried an SED Winged C tube and the difference was beyond stunning. Absolutely no comparison..the SED flat out destroyed it with a far richer, far more dynamic sound with unspeakable beautiful complexities in the mid frequencies. If you're looking for that famous Marshall crunch this is not the tube.
Mullard EL34 | My Choice EL34
by Daniel
Nothing for me not to like about the MU-EL34. They are quiet operation and biased just fine in my prs hxda 30 head. The Tube Store 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.
Mullard EL34 | Lackluster Performance.
by Paul
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.
Mullard EL34 | Marshall + Mullard = Melodious
by Joseph Weldinger -
I purchased a matched pair of these MU-EL34 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 (Shuguang 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.
