This Preferred Series EL34 tube is a premium high quality tube produced for us in China by the Shuguang factory. We found the best of current production, sourced it to our specifications and gave it a 6 month extended warranty.

The Preferred Series EL34 construction features:
- Grey plate and single "disc" style getter
- Gold grid wires
- Copper grid posts
- A carbonized filament for more efficient thermal radiation
- Low noise filament
- The bottle is made with a heavy gauge glass
- And finally the blue color base is a nice touch too!

From our review: The bottom end is amazing and the tube has tons of gain before it gets dirty. The real strength of this tube is the bass and midrange. Bass notes are rock solid and the mids are very rich and complex. The high end is very good but not bright. This tube really wants to be in your JCM 800 or other amp that can generate piercing top end."

"The Preferred Series EL34's have an incredibly tight bass response, unparalleled clarity, and are very rich in harmonics. They are perfect for what I need out of my Diezel VH4 guitar amp. In combination with the Preferred Series 12AX7's, these tubes have brought my Diezel VH4 back to it's former glory. Many thanks to!"

Classic performance, solid construction


I had to grab a pair of these to see what the Preferred Series brings to EL34's. After some playing time with these tubes in a modified Traynor Bass Master, I'm impressed!
Visually, they look great, with a bottle that's a bit larger than an original Mullard EL34 and a plate that's also bigger. The bigger plate should improve power handling and the plate is welded not stamped, so that should keep the microphonics down.
Play testing... there's a lot to like! The highs are clear, not edgy though. The mids are good, if anything, leaning a bit to the 'Brit' side. But the bottom end, solid and chunky. The finger on string stuff makes it to the speaker and these tubes help it along. I'm a bass player... what I hear works for me and I think guitar players will get a lot out of these tubes too.
Well worth a try!

Warning! You'll want to play these loud!


I took a chance on these and I'm glad I did. They do the job on clean, but they're so hot on medium and high gain, I'm not sure you won't care about your clean channel. I put these in My Suhr PT 100, which is basically a plexi style 100 watt amp. These EL34s take the roof off! I liked the Tungsol Gold 12AX7s in my smaller Suhr amp (Badger 35). So much so, I robbed those three tubes and added them to three more matched to the PT100. I have the gain on the mid channel at 4, and the high gain channel on 6. It's just wailing! Earplugs or an attenuator are in order here. You're just going to want to turn these EL34s up. I like how the bass and treble roles off nicely. This is the best tone I've heard for a 7 string. I hate boomy lows and spikey highs. These EL34s are clear and articulate. I'm not getting a grungy character here. What I'm getting is a well rounded tone which works really well with modern speakers like the Eminence CV-75s. These tubes are very refreshing if you're tired of vintage vintage vintage.What they lack in grungy old fashion character, they make up with hot screamin' gain tone. And not over the top and scratchy like some expensive NOS tubes. I'm not sure I'd recommend these for a new Marshall unless you want to go from traditional to modern. But for an old style plexi amp where JJs sound raw, these are smooth and scream. Very good quality and beg to be cranked up on high gain. I didn't get any weird double clipping with my Seymour Duncan Jazz, or Alternate 8 pickup. So they handle a bright modern high output pickup. I hope they last, because I really like these. A wonderful tube. They don't crap out with high output pickups. They're a modern sounding tube without grunge character. But with only a few hours of playing time, they may sag up. Yay thetubestore. Not a traditional sound, but not stupid over the top either.

A stellar addition to the Preferred Series.


I'm a growing fan of the Preferred Series from The Tube Store, and these EL34 tubes just add to my positive experiences with the series. I put four of these into a 10 year old Mesa Roadster and the thing just came to life! I had found the amp to be a bit boomy and shrill, but these EL34's balanced everything perfectly. I even prefer the clean tones I'm getting over the 6L6's that were in there before! Now the bass is tight and responsive (for a Recto) and the treble is smooth, but with bite.
These EL34's are tight, clean, and powerful; their midrange is complex and harmonically rich. These will be the EL34's I recommend to everybody. Couldn't be happier.

Great Tubes!!


I recently purchased a set of these for my Marshall DSL40C and just had them installed. These tubes along with Tungsol 12AX7 (V1) Preferred series 7025 (V1,V2) and a Sovtek 12AX7LPS (V4) made a huge difference. I had run the pre-amp tubes separately along with the stock power tubes first and they made a big difference alone, but when adding the Preferred EL34's it took out almost all the hiss on the lead 2 channel. The amp even sounds louder and fuller now than it did before. I would highly recommend these tubes.

The EL34 Ive been looking for


I have a KSR Colossus amp and tried the Mesa Boogie matched set of EL34's and took them out because they didn't sound good in this amp. Went back to JJ 6L6GC for a year and then I tried these Preferred Series EL34's, wow, sound immense, I think Ive found my tubes.
