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 thetubestore.com!"

Ratings & Reviews
GREAT IN MY DECWARE TORII JNR
by David -
I ordered a quad set of these Preferred Series EL34s for my Decware Torii Junior Hi Fi amplifier. I am very impressed. They sound very, very good. The sound stage is very wide and full, the bass response excellent (and they are still to break in), and the imaging is very good. A definite improvement on the Svetlana tubes that came with the amp. They came to voltage (bias) easily and run very stable. I can highly recommend these tubes for other Decware owners. Great tube sound without breaking the bank.
What a Difference in my Marshall Origin amp
I replaced the stock EL34 JJ's in my new Marshall Origin 20 watt combo amplifier with these Preferred series EL34's.
The results were a richer fatter low end with even balanced mids and buttermilk smooth clear highs. A definite increase in clean headroom.
These have a slightly fatter bottle and thicker glass than the JJ EL34's. I also replaced the stock JJ 12AX7's with a Jan-Phillips 5751 in the V1 and a Genalex Gold Lion 12AX7 in V2 and a Genalex Gold Lion 12AT7 in the PI.
The difference was clear from the time I turned the amp on. Jon guided me in the right direction and dealing with him is always a pleasure.
My Marshall Origin 20 Watt combo is just killer sounding now thanks to these Preferred Series EL34's.

Holy Crap!!! Deep Bass, Clear Mids, Smooth Highs...WOW! Highly recommended!
Expensive experiment in Mesa Boogie
The first set I received sounded good for around 30 seconds before smoke billowed out of my Mesa Boogie. Around a week later my guitar amp tech told me both tubes tested out OK on his tester, but under full plate voltage one of the tubes shorts out. He also said the same tube was very touch sensitive where he could make it short out in the tester by tapping it. Anyway my tech told me the tube smoked a power tube screen resistor and melted the insulation of a couple of wires. Told my story to the tube store and they sent out a new set free of charge but didn't offer to pay the $160 bill from my amp tech. The tech did put in a new set of Mesa EL34s for an additional $61.00. Figured I would keep the warranty replacement Preferred Series EL34 set as spares. I did however decide to test them out and they played good but preferred the Mesa set.
MADE FOR A JCM800
by Mike -
I build JCM 800 kits. I finally jumped at these and man.... Nice tightness and smooth top end. I sometimes have customers want 6550s that are more spendy. With these the bass is there and a really nice midrange grind. I'm hooked on these. The preferred serious pre amp tubes are great as well.
