In a different post someone mentioned Mr. Wronski runs EL34s. After much searching I found the info in the "top 10" section. I love Vox AC30s and amps of that ilk, but also love Fender amps, and I was wondering what kind of mods it takes to be able to run "british" tubes in a Fender amp. Can you go back and forth without much work, or is it a "mod it and leave it situation?" A bandmaster or bassman, or heck a nice deluxe would fit into my life rather quickly if the answers to this question make it sound easily doable! I did poke around a bit before asking, but haven't found anything here or any other site I go to. Thanks.

Runs EL34s in what? AC30s use four EL84s, not EL34s.
EL34/6CA7 uses the same octal base as 6L6GCs, but are not pin compatible. It would be a very minor modification to the bases to allow EL34/6CA7s "work" in Bassman/Bandmaster/etc., but there are other considerations. First and foremost, EL34/6CA7s draw much more heater current than any 6L6 variant. This places greater demand on a PT that may not be rated to supply the increase in current. The electrical characteristics are each tube type are different, so much so that other modifications will most likely be needed. Further, I do not think that a pair or quad of EL34/6CA7 would be all that happy seeing the same primary impedance as a 6L6 variant. I would say its a "mod it and leave it", but I wouldn't mod it at all.
As a matter of opinion, I doubt that an EL34/6CA7 will take a thoroughly American guitar amp and make it sound "British". God, I hope not...

I'm basically saying I like "EL" tubes. I also don't want to make it sound british, I just want to split the difference, and make a "hairier" bassman tone... Clearly I need to talk to a tech... Check that, a really really really good tech...

Why exactly? To sound like Dave?
I wouldn't do anything if I were you until you understood what exactly the difference between a EL34 and 6L6 is and what tonal characters those two different tubes can provide.
If you do know then you should do whatever you wanted to do before you asked us. Don't listen to the naysayers.

Jake, in case you haven't noticed, I don't care what anybody here thinks, HOWEVER, I do respect each individuals different experiences and knowledge base. I personally have my own experiences and knowledge base, and I am WAY too old for hero worship.
Some folks here are about as tech savy as they get! I was asking a technical question to find out if it is even worth taking the steps to find and talk to a capable technician about doing it, or if it's so complicated that they would put a garlic necklace around their neck and start flinging Holy Water at me...
Since I first picked up a guitar in '75, I've owned Fender deluxes and twins, Vox AC15 and AC30s, Roland JCs, Marshalls, and at least a half dozen cute little no name amps from the 40s and 50s. That's not counting the acoustic amps I've gone through. I know what they sound like. I don't particularly want to own more than two amps. You are a self confessed "amp guy". Me, I like guitars. I'd rather own more guitars and I want exactly what I said, a Bassman tone with more hair on it. I play lots of stuff and an amp that can handle everything from Cake to Link Wray, to lightnin hopkins(through an old dry acoustic with vintage dearmond soundhole pickup) and old Johnny Guitar Watson without pedals is my goal. I use Guitars like pedals. I have piercing icepick guitars, and I have smooth dripping buckets of warm honey guitars... That's how I like to alter my tone.
I don't particularly want to "sound" like Dave. As I said, whether you believe it or not, I've already gotten a passable tone for that. And when I listen to Dave, his tone is irrelevant to me. I listen to his masterful picking. His precision and ability to seamlessly throw in polyrythms, shifting back and forth between straight 16s and triplets, "turning the beat around" reminds of me of people like Bob Brozman. Very rare in the electric world. Not to sound pretentious, but I'm sure alot of people are unaware of what he's actually doing. Like Chuck Berry, there's more going on than you think if you aren't careful. The melody is often deceptive. I don't particularly want to play like Dave by the way. I like more space in an arrangement. As the king told Mozart in "Amadeus", there are too many notes for me...
So anyway, It sounds like more of battle than I want to enter, and the new Mesas are going in the direction I want. Not quite what I want yet, but it's only a matter of time before someone nails what I'm looking for...
Peace Brother, I know what I want, I just need to find it...

If you want the british tone there's no need to mod, if you want a fender / vox vibe just change out the speakers to Vox blue bulldogs or silver ones, last year when we played with slacktone @ HBISM Dave Wronski gave me a personal tour of his amp rig and set up and showed me the back of his combo super reverb "Slacktone amp" and I saw a mix of silver vintage Vox speakers and he spoke about tubes, Dave & Dusty are just the coolest he also had me to try out his hybrid strat/jaguar axe and that thing was pretty dang cool
Pagin' Daveslacktone, Pagin' Daveslacktone: I can't seem to remember if you mentioned you had Vox speakers or stock Fender in your 62 bassman cab???

I don't use el34 tubes, I use e34l. It's a Euro style 6ca7 that has 20% more headroom than a el34. I use the new JJ, and have some of my amps using Tesla e34l, which is basicaly the same thing. I've been having the best luck buying JJ e34l from GrooveTubes.
My Super Reverbs {except one} use the e34l power tube, but the amps have other changes, too. The bias is very "turned on", and approaclass class A. This, along with the grid resistor{I think} value being different which would normally cause cross-over distortion, but has other good qualities. The amps have a special mod the prevents them from being capable of producing cross-over distortion, so the bias can be set wherever my tech finds the sweet spot. This configuration gives the clean single note a more robust sound, to quot my tech.
Even without all the trickery, the e34l is a cool power tube that gives me a little more power, has smoother overall tone where the bass does not boom so much as with a 6l6.
I even made Pete Curry a believer when he had them installed n his '61 Bandmaster combo amp with the JBL D130. The Telefunken 12ax7's don't hurt either. YMMV

I would think the transformers, capacitors, and other things would make the tube a little dirtier more than the EL34 without a HUGE mod. Also you can get these things called yellow jacket tubes that cut the power a little. I've never used them as I would be happy with a pedal to color my sound.

anyone here, let alone a really, real contributer... check that, a real thankless asshole of a contributer...

Whoa there big fella! My comment about "Clearly I need to talk to a tech... Check that, a really really really good tech..." Was not doubting your knowledge. It was stating that based on your answer, which clearly demonstrates indepth knowledge light years beyond anything I would ever hope to have, if I were going to try to pull this off, I couldn't just run down to "Bill's Vacuum Cleaner Repair and Amp Fix-it shop", that I would have to find a highly experienced and creative tech to do the work! I don't doubt your abilities, and if you lived anywhere near me, I would either hire you to do it if you do amp repair, or hire you to talk the folks who would be doing the job to make sure it was done right
Frankly I'm not an asshole and realize that internet communication is often unprecise. For instance I found Jakes answer incredibly insulting. But I know that people of his generation have a different communication style in electronic media. There messages tend to read like "RainMan" monologues with no attempt to be civil or polite. I thought I would point out to him that I've been playing longer than he's been alive... And contrary to his previously stated belief he doesn't have wider musical than just about everybody here... I don't think he's an asshole. I think he's young. Nothing wrong with young. I used to be that too.
I try to help others out by pointing out good deals or good equipment when I see it. I don't call people asshole. I hope I cleared up any misunderstanding that came out my message. If I didn't, hey like I said, I don't care what you think. I do however respect what you know and I respect your right not to like me. I'm also happy to be help support a Forum that lets you call me an asshole. Why that would matter to you, I'm not really sure. I try not overly analyze hairs that up people's A**es

Badash really really bad choice of words we all need to be more laid back
Daulshowman is a kickass Engineer/amp tech, back in the day I was always emailing him on advice and he comes through with the info you need an awesome help when I was starting out with my amp ventures and repair, there are plenty of excellent amp techs/guitar techs here @ SG101 and Dualshowman aka Matt is one of them and DGG of Gomezamps and there's probably even more that we haven't even discovered in this forum or that have come forward yet, we need to give these fine folks a chance and have them express thier expertize and then research then make your call before you offened others that are in the trade in making a living from servicing amplifiers or just say nothing keep the insults to your self and thank them for the feedback if its not to your liking or what you wanted to hear move on, the worst thing is to make enemies and you don't want that my friend in any place, were here to learn and to help others learn and to share the things we know about amps and guitars and most of all the music... not to be-little or bash or to even put down but to help each other out.

Kyle, see my answer above. I should have said GO TO a really really good tech to HAVE IT DONE. I'm only restating it here in case you and Dual don't see the above message!

I'm talking height wise. I think they are too tall. Have other responses included that fact?

Are they too tall? I couldn't find any other posts on this. I tried to reread most of the thread but got distracted(WWI Trench History). What am I missing? I know nothing about the size of EL34s except they look bigger than a 6L6 although they could just be skinnier.

We've moved on now Jake. The post has been redirected to how much of an asshole I am. See you're a history major, and we're now talking current events.

No matter it's in plain enlgish and to my eyes you made it clear that you basicly don't think Dual's or for that matter anyone else's info was not credible enough so you clearly said I qoute "Check that, a really really really good tech" so I can see where he got offended and
to anybody reading your post will be thinking the same thing right off the bat so you see now
Why even ask for help or feedback?
it's all there I can see it man
Just as you read Jake's lingo wrong in the past as you mentioned this can pass as that as well, that things can be read wrong or taken wrong, before you hit "Submit" think about it, and man I don't want to make bad blood it's not my bag I just hate to see 2 fine folks go at it or folks in general @ SG101 mis-understanding each other, the damage has been done with Dual but I hope he comes back?
