Members K-Bizzle Posted January 8, 2009 Members Share Posted January 8, 2009 The reason I ask is both of these tubes always seem to be touted as "A good mix of EL34 and 6L6". So I basically was just wondering the differences between the two and if anyone has compared them. IIRC JJ is the only company that makes E34Ls and are one of the only 2 companies making KT-77s, so I think its a fair comparison as I would assume most of you who are using KT77s aren't shelling out $200 for a set of gold lions. Thanks. Link to comment Share on other sites More sharing options...
Members vrm Posted January 8, 2009 Members Share Posted January 8, 2009 I haven't compared them both but do run the jj e34l in my ampeg and they do have a bit more bottom end than the el34's that were in there before. Link to comment Share on other sites More sharing options...

Yeah I have a set of E34Ls myself. I stopped using them cuz they were old and because I was mixing EL34s and 6L6s in my RM100 anyway. Basically the reason I'm asking is my RM50 can only run a pair of tubes rather mixing like I did in the RM100, so I'm hoping to get the best of both worlds in one set. The real issue is, that the current production JJ KT-77s are said to be crap by users and dealers alike. Link to comment Share on other sites More sharing options...
Members peehoo Posted January 8, 2009 Members Share Posted January 8, 2009 Bump for interest in this. I was inquiring a similar thing. The E34L, the 6CA7 and the KT77 are all supposed to be between EL34 and 6l6. So it would be interesting to know what are the differences between those. I'm gonna have to retube my EL34 based amp soon so this question is hot... Link to comment Share on other sites More sharing options...
Members vrm Posted January 8, 2009 Members Share Posted January 8, 2009 I don't really find the 34L to be that 6L6-ish other than a bit more bottom end than the regular el34s they replaced. Link to comment Share on other sites More sharing options...
Members Giga Posted January 8, 2009 Members Share Posted January 8, 2009 I've put JJ KT77's in my 2/50/2 which has EL34's stock. Bigger, rounder bass, less harsh mids and highs. I really like them in that particular amp. I've had one go south but most likely that was my own fault. Never had any other problem with them. Giga.

Members vitod Posted January 8, 2009 Members Share Posted January 8, 2009 Haven't tried KT77, but I have EL34L in my JCM800. Clarity improved, tight, bigger bass, smoother mids were the result. So, I'm a fan. Link to comment Share on other sites More sharing options...

I have ones dated 2005 (JJ's) and they for sure are NOT crap? In fact, theY are pure tone win. I guess the "current" referred to is more current than 2005?

Members .homewrecker. Posted January 8, 2009 Members Share Posted January 8, 2009 6CA7:mad: Now I've gotta have another to choose from now, great. Go for the 6CA7s, I have them in my JMP and they rock. They're a mix of 34's and 6550s more than 6L6s IMO. They have that mid grind of the 34s, same top end of a 34 but they have the ass end of 6550s. EH is the only current producer and it's they ONLY tube of theirs I like, and they are CHEAP!

I guess the "current" referred to is more current than 2005? Yeah past 3 years have been crap is what people are saying. Heres a quote from the webpage of a guy I buy from locally sometimes. Lousy build quality - I won't use 'em in my own gear, so I won't sell 'em! I won't be stocking theseuntil JJ gets the build quality improved significantly. Very disappointing... This kind of stuff is why I haven't pulled the trigger on them. Link to comment Share on other sites More sharing options...

Its ridiculous when people buy into internet opinions then become convinced there's a "real issue" about KT77s or that they're crap. Not sure why some folks believe everything they read on the internet. I bought my JJs back in July 08 and they have no issues. Like alot tone tweekers I compared the JJ against four other el34s. GT EL34B SED el34 c wing EH el34B Telefunken el34 anos The Telefunkens by far sounded the best, then SEDs then GT and JJs were a tie. One thing is they weren't crap.

Members MetalHeadd Posted January 8, 2009 Members Share Posted January 8, 2009 I've tried both the JJ E34Ls and the JJ KT77s in my Marshall JCM900 head. The E34Ls sound very much like EL34s, but with a little more omph in the bottom and a very raunchy midrange. The KT77s had a huge bottom end, a more evened out midrange and rounded off highs, and in general sounded very hi fi to my ears. They worked really well in a live context, and I highly recommend them. I plan to install some KT77s in my JSX as well. Link to comment Share on other sites More sharing options...

JJ KT77s aren't crap and posting that is pretty ignorant. You just happen to believe in internet opinions that are based on crap. Risk ?............. exactly what are you risking What ever the brand or type of new production tubes you buy the risk is pretty much the same.

Members starsnuffer Posted January 8, 2009 Members Share Posted January 8, 2009 I've compared them both in my Bogner XTC and my Triamp MkII I prefer the KT77's, thicker, chunkier, with more well defined highs. However, recently I tried again with new KT77's and preferred the EL34s, turned out that after several tries I couldn't get a matched quad of KT77's and no matter how I set the bias they sounded harsh. If you can get 3 year old KT77s or new Gold Lions, go for it, if you have to get new JJ tubes, get the EL34L's -W Link to comment Share on other sites More sharing options...

Whoa. ok. stop. "build quality"?? So in other words if you get four working and matched tubes the tone is still there? Oh man, buy the tubes, seriously.I'm not even sure I buy that. (although one of mine did drop a pin on first install, but once replaced, they have been working great after a month of abuse in my JSX combo).

When I compared Jjs in my Vox AC100 the JJs compared equally to SED and GTs el34b low and high end. Its just the midrange wasn't as complex and clear or juicy. There's no proof that the 3 year old JJ KT77s are superior and the newer JJs are crap as previously stated, especially from anonymous interent sources.

In a nutshell KT77's are like- 6L6's in the bass/treble/presense/resonance EL34's in the mids. Might a bit too simpley stated, but you get the point.
