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!"

Preferred Series EL34 | What a Difference in my Marshall Origin amp
by Ed
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.
Preferred Series EL34 | 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.
Preferred Series EL34 | One of a kind power tubes.
by Just In Beeper
I have Marshall Tsl122 and used quads of JJ kt77 and Shuguang EL34s before. Kt77 had huge bottom end and were less compressed than EL34, sweet sounding lead sound. EL34 shugs are very hot crunchy VH sound and much tight bottom end. After not much use I had trouble with bias drift with both quads ,i.e one or more tubes becomes so hot. So I ordered the PS-EL34 quad and even on the first use I was very surprised to hear KT77 characteristics of huge and big bottom end and nice compression which was much sweeter than the regular EL34. I feel that mids are not as high as regular EL34 but the low and high ends are elevated which make every note sound huge.
Now I don't have to worry anymore about the BIAS problems . And my amp become a new kind of animal. One down side is that I had to turn a tad more volume than before because bedroom level volume does not do them justice. Worth every penny.
Preferred Series EL34 | More of everything
by Albert
Great tubes with really big sound especially on mids with bold percussive lows. Highs are smooth. Have 2 PS-EL34 installed on my THD Bivalve 30 watt class A amp with 2 nos Mullard 12AX7s. Sound is very powerful as I run amp on full power all the time. Very quiet. Push the front end with Fulltone Plimsoul when I need it. Have the head going into Bad Cat Unleash 100 watt power attenuator where I run my delay through its effects loop. Best sound ever. Notes are thick yet cut through. Sounds very Mashall going into Traynor 2x12 Greanback cabinet but with more complexity than any Marshall I've ever played and with much less noise. These tubes are very reliable as I only run my amp dimed and these tubes just shrug it off like a walk in the park. I've had nos el34s and these hold up very well so I'll just get these when I need a change. So far they sound like new after a year of everyday use. Very pleased.
Excellent all rounder
by Gordon Jonathan Lewis
Just bought a quad set of matched Preferred Series EL34 for my stereo VTL ST85 amplifier, to replace the stock Electro Harmonix. Now, don't get me wrong, the EH is a great tube, solid, reliable. But I think the Preferred is a notch above the EH - impressive deep end, very nice midrange and an upper end which is just right without being too edgy. Highly recommended.
