Are there any 6L6 power tubes that get close to the tone of EL34 tubes?
Typically not a trait of tubes in my experience.
Easiest thing to do is get a Celestion speaker with a lot of high mid emphasis, V30, Gold should the trick. Chasing around tubes is not the answer.
Not exactly, but the JJ E34L might split the diff. It's kinda in the middle tone wise.
KT77 if your amp can run them.
The KT77 is a blend of a 6L6 and EL34 but if you can run a KT77 in your amp then you can also just run an EL34 if that's what you are after since the KT77 and EL34 are direct replacements for each other.
If you prefer the "EL" tone your best bet is to just get a new amp.
Kt66's give you a bit of the el34 crunch but still nothing is an el34 except an el34.
Both KT varieties draw more filament current, though, and the 77s expect a plate load similar to that of the EL34. Those and the 6CA7 do however work w. an octal socket using some pins for tie-off points, per some Fender amps and similar.
I think the TAD 6L6GC STR had a mid range quite reminicient of an EL34 with nice mids and bite. I used it for Marshall lead a good while before I converted my Marshall to go easier on the grid. 5881s and similar can have a rather swirly breakup pattern, perhaps similar to the EL34 and KT66, as well. But whilst these have some properties in common with an EL34, you won't find the roughness and fluff of the EL34 in a 6L6 spec valve, as their Gm and principle of operation is quite different.
Btw: may I ask the nature of the amp the 6L6s are supposed to go into and the intended purpose?
Looking at it from the other side of the equation, I've found NOS/ANOS US-made 6CA7 tubes to be the most 6L6-like EL34 tube - more rounded/less strident in tone than a straight up EL34. The Sylvania 6CA7 tubes are much sought after and very pricey these days, but GE 6CA7 tubes can be found at reasonable prices if you're patient, and they sound great. My 2 cents.
Try different speakers/cab. Last element in the signal change and biggest tonal contributor, in my experience. Plus, a new cab. Win-win.
Sure -- it's an EVH 5150III 50w head. It uses 6L6 tubes, and I was curious if there were any "EL34-like" 6L6 tubes out there.
what amp are you using as a reference point of what el34s sound like to you?
the vox ac30 and the marshall class 5 use el84s and they couldnt sound any less alike.
I always thought the Sovtek 5881WXT had a little more midrange grind to it than most 6L6GCs.
What about some EL37?
I think it was Eurotubes that used to sell what they called an "Integrated Quad." If I remember correctly, it was a set of two EL34s and two 6L6GCs that you supposedly could run as a quad in some amps.
This isn't something I tried or am recommending. I just thought it might fit the bill in light of what you are searching for.
Tubes don't have tone. Amps have tone and an amp is composed of a circuit, transformers, rectifiers, preamp tubes, power tubes and a speaker. And they still don't make any sound until you plug in a guitar and play it. With your fingers.
Power tube choice is the last 1% of the way your amp sounds after a long list of other things. Putting an EL34 in a Twin (along with required circuit modifications) isn't going to make it sound like a Marshall. It's going to sound like a Twin with marginally perceptible differences in gain and responsiveness from before you swapped tubes.
I believe the 5150 is supposed to handle the higher filament draw of ELs, KTs and 6CA7s, so as long as they fit you should be OK. They may be wired not to support true pentodes, like the EL34s, though so wouldn't fit those. And should the grid resistor in place be with 6L6s in mind, then KT77s may be over taxed as well. 6CA7s and KT66s seem to survive rather well though, as long as they fit.
Pedantic excursions abound.....
The question, as stated, is mostly meaningless. That's all.
