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."

JJ EL34-II | Great tube for great price

JJ EL34-II | Noticeable hum
by DD
Maybe I got a bad set, but these hum noticeably in my amp. The sounds was OK, and I played it for a while like that with no issues but kind of annoying. I tried a couple of old sets of EL34s I had (JJs/Svetlana and Tube Amp Dr.) and the hum was not there, so it's not the amp. Bias was adjusted the same for all the different tubes I tried.
I am a new fan..thanks for the fast shipment

These tubes are very nice - they replace a quad of 2 yr old EH EL34s
JJ EL34-II | Warmed up an Egnater Tweaker-15 Head
by Chaz Eton
Great tubes! That's the short story.
Long story/personal application: I have an Egnater Tweaker-15 head, great little amp. I'm running it through a JSX- 4x12 (bought used). For one reason or another, the 6v6 stock tubes were just too bright for my ears and I couldn't dial the brightness out.
After much research, I landed on these JJ-EL34-II tubes. MUCH improved sound over the stock 6v6s to my ears, and much warmer and better crunch. The EL34-IIs barely fit in the head-case, but they WILL fit.
I run the Egnater on the Vintage British channel, hot, normal/tight.
JJ EL34-II | Closet to NOS you can buy
by Ricky
My go to tubes for my Blackstar HT Club 50 MKII. I recently gave JJ another try and I am so happy I did! All the new production Russian offerings just did not do it for me. Seems like all just rebranded Sovteks. I'll stick with what JJ has to offer for all my tube amps! Get yourself a good balanced set of these JJ-EL34-II and you won't be disappointed!
