EL34 & 6L6 characteristics


I finally got my garage sale tubes tested out , thanks bigshutterbug !
I rolled in some EH 6L6's in place of my EH EL34's to compare . About as close to apples-to-apples as I can get .

I am asking if there is a tube that combines the characteristics of these two tubes ?
I like the warmth , body and bass of the EL34's and the top end , detail and air of the 6L6's . Is there something that would have all of these characteristics in one tube ?
Yes , I want it all !

Thank you

I bought a used pair of Quicksilver Mid Monos a few months ago. The previous owner changed out the EL34 tube with 6L6g Tung Sols. I thought they sounded very good.

I previously owned a VTL 50 watt amp that used 5881/6L6 tubes, it was a nice sounding amp but it died and I replaced it with an Anthem Amp 1 which was a 40 watt EL34 design. I had that amp for a while and preferred the EL34 sound.

Recently one of my Mid Monos had a 6l6 that died, I replaced the tubes with the original type the amp was voiced with, EL34 and am really loving the sound. Quicksilver OEMs are Chinese EL34, but I was anxious to get the amp up and running again so I picked up a matched quad of EH EL34 for $65....

The great thing about the Mid Monos is that they can use many different output tubes so I'm sure I'll try something else but for now these EH tubes sound great.

" and (too muddy) EH tubes." Now that kind of rings a bell here . I really liked the EH EL34's warmth when I was looking for that . But now that I hear the clarity and delicacy of these 6L6's ...ding ding ding !

On the Shugang's...from what I have been told , these Ruby's & Mesa's were rebadged for guitar amp sellers so as to have an 'exclusive' brand for their store . I have read that some of the tubes , for guitar amps , were of lesser specifications due to the desirability of some distortion .
Opinions anyone ?

The more that I listen to these 6L6's the more that I am enjoying them ! Tommy James & the Shondells just came into my room and are playing Crimson & Clover !
Man I love this stuff !!!

David, no matter what anyone claims, everyone gets the same tubes from the Shuguang factory. They do not release better or worse versions. When they pass QC, they're good tubes. Again, in my experience, Shuguang produces the most rugged and reliable tubes currently. As you noted, once they go off into the world, various entities screen their own names/logos on them.

If you decide you like the 6L6 sound best, go with it!

I'd still give the Shuguang EL34s a try, just to see how you like them. Normally, I need to listen to 2 or 3 variants before passing judgement on a tube type. EL34 should normally provide good detail.

By the way, I presume you own the Shuguang EL34B variant? You can tell by the fact that they have a reddish brown base. Their original, EL34 (EL34A) have a black base, and do not sound nearly as good.
I really like the Shuguang EL34B. That surprised me. I liked them better in my Coincident Dynamo 34SE than some NOS that shall remain nameless. I am really enjoying the Shuguang Black Treasure 6CA7 even more so.
Joe ;
No , unfortunately the EL34's are Ruby EL34LCZ with what appears to be a black base !
The JJ's are EL 34L's with a Tube Depot paper bias label on each base . I have 2 tubes packaged together with a sticker identifying them as a matched pair .

The Mesa Engineering are 6L6 GC and under the Mesa logo is STR 430 . These are listed on the base as 'handtested in amplifiers and computer matched' . I have 3 box's of matched pairs and 3 individually boxed tubes .

Mikirob ;
Glad to here that you are still enjoying the Dynamo .
Have you tried any other 6CA7's ? If so , which ones ?

Thanks
