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 new JJ EL34-II power output vacuum tube is now available. Great classic rock tone for a reasonable price.

From our review of this EL34 tube: "JJ has upped their game with the new EL34-2, and the design change is truly big enough to warrant the use of the new name. I found there to be a really nice top end that is smooth and free from harshness, while still delivering a nice bit of sparkle. At the other end of the spectrum I found the bass to be very firm and clear with no boominess. For guitar use the midrange is where the action is and this tube handles it nicely. I didn’t hear any honking mids."

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.

I'm surprised! Great tube!


I just wanted a cheap quad of EL34's to use while working on an old Rivera TBR-1SL. And although these are really inexpensive, they don't sound cheap at all. The bottom end is both plump and taught; the mids are clear, present, but not overly rich; high end is clear and clean. All four tubes biased within 1mA of each other!
I'm happy enough with these new tubes that I'm leaving them in! I've only put ten hours in on them so I'll report back in a few months on how they hold up. As for their tone - I'd recommend trying some!

Excellent value for money!


This new version of JJ's EL34 is very good, not only in relation to its rather modest price. The tube is very balanced across the whole frequency spectrum, with a general tendency to a slight leanness (which I like). The mids are smooth, and the highs clear, but without sharpness. There is no bottom-end boom or thickening of the lower mids. I use the tube in an audio amplifier, by the way.
