Tube Shootout: Shuguang EL34B vs. Mullard xf2 EL34

How can you get a great tone without a good understanding of what makes your amp tick? — EL34, EL84, 6L6, KT66, KT88, 12AX7, 12AT7, 12AU7, EF86, Output Transformers, Power Transformers, Capacitors, Resistors and everything else that it takes to make a tube amp sing!

and what about the headroom compared to xf2 or other tubes?
i remember when i put out xf2 for sed in my marshall i've to go up from 7 to 8 to have the same saturation...

Oh yeah, I forgot to mention that, thanks. The Shuguang seemed to have a little more headroom, but not a whole lot more. Like I said, they're two entirely different tubes.

Well I've had the 34Bs and the GT 34Ms in my Jubilee. And I pretty much agree with TG's assessment. The 34Ms do sound more Mullard like and the 34Bs stay cleaner longer. I have XF2s in my 2204 so I'm very familiar with how they sound. I can get my Jube to sound closer to my 2204 with the 34Ms but at the expense of more diode fizziness. I can dial out much of the fizzys with the 34Bs and get bigger low end but the amp stays cleaner with more sparkle and loses the upper mid snarl of a Mullard. To some that may be a good thing.

I guess it boils down to pick your flavor.

WTF is that???????? 2006?

For your info ValveArt both over haft a million of the 6th gen Shuguang el34B and those are not from early 2006. They are at least 2-3 years old made, around 2004 not 2006....So lots of left overs all over the place.....

What we would like to know is the current issue of the Shuguang el34B 11th gen tube that is available directly from China. Could you please stop scamming people around with that bullshiat 6th gen review and use the actual Shuguang being made.........

Oh no, it's the stalker. I meant to say 11th gen. from 2006. The date on the package was 1/18/06. If they're made this year, I think everyone gets the point that they're the latest version.

does the review contradict your personal experience with them? there is a confirming opinion already posted, so I'd be curious to know what you think is not right with this review - especially considering your ...... emotional :roll: response to an opinion of a piece of glass readily available for around ten bucks.

Thanks for the review Tubegetter, and thanks to Vic for providing the test bed. This has maybe given me a load more questions to ask, than answered, but its all good. I was kind of sold on getting EL34Bs, but maybe its the GT EL34M i need for my Superlead. Well, i'll search around this forum for other reviews and see what comes up.
Cheers :D

This was a solid review. It was exactly what I found to be true in my experiments with these tubes. Ultimately, I found them a litt;e hard on the ears so I'll stick with Mullards or something else. But good tubes for sure, just not my favorite for EL-34's.

Wow. I did a search for el34b vs el34m and came up with a ten year old post from our group, lol...

I think I'm gonna go ahead and get a quad of the shuguang selected and matched el34m. those are $65 a quad, much better per tube than $42 for two.....

what the heck, it's only money, right? :mrgreen: I just can't risk being killed in the middle of the night by Ms. Unit when she finds out I spent $250 on a pair of xf2's :lol:

(I sort of split this post in two, with the first half of it being near the bottom of page one on this post:)
