Members JamesPeters Posted February 24, 2008 Author Members Share Posted February 24, 2008 So lets end the hype. post clips of the same amp with kt77's ----then El34. then el 34L . etc... i know you can do this james..... if not--im going to do this soon to end the power tube " mysteries" . Tell you what--knock yourself out. I stopped using JJ KT77 in my amps a while ago because they were too polarizing for most of my customers. If they expected the sound of a classic EL34, they were disappointed. If they expected the sound of a 6L6, they were disappointed. It was only those with an open mind about it who appreciated the JJ KT77 and learned why they were good for what they were. I still like the JJ KT77. I just don't want to mess around and lose the "first impression" battle because the tubes are "too middle-ground" for most people's tastes.

Members Oblivion DC Posted February 24, 2008 Members Share Posted February 24, 2008 That's up to you. At the time I posted this thread, they were brand-spanking new. By now you should've gotten off your lazy ass and tried them yourself. Tell you what--knock yourself out.

Do you happen to know of anyone else who currently makes a KT-77, other than JJ?? Link to comment Share on other sites More sharing options...
Members The4thlast1 Posted February 24, 2008 Members Share Posted February 24, 2008 Exactly.............. It is kinda hard to get a good judgement on Kt77's when the only production out there seems to be JJ's. In general I don't really care for JJ tubes they seem to be dark and a bit muddy to me. Is there any other Kt77's out there in production now? Link to comment Share on other sites More sharing options...
Members -DOOM- Posted February 25, 2008 Members Share Posted February 25, 2008 Thanks. Well, like James said this seems to be what I was looking for in a 6ca7. I wanted to replace my EH but there doesn't seem to be many currently produced 6ca7's out: Electro-Harmonix, Ei (i can only find them sold in singles), and GT General Electric reissue (temporarily out of production). But if this tube does all James is saying, I'm all about it. Any other noteworthy KT77s? Hey mate - If you decide to go down the KT77 road, I'd be very interested to hear your impressions...FWIW, they are meant to kick serious arse in Rocker 30's as per the Orange Forum....Cheers:thu: Link to comment Share on other sites More sharing options...
Members kmanick Posted February 25, 2008 Members Share Posted February 25, 2008 I've got KT-77's in my JSX head and I think this amp should ship with them. To my ears anyway they take the best of What El34's have to offer and the Best of what 6L6's have to offer and meet somewhere halfway. With KT-77's in the JSX there is no upper mid spike and the bottom end is a bit fuller. I'm going to order another set and try them in my Rectoverb head, as I have El34's in it right now and I really like them, but I also like 6l6's in there so the KT-77's should make me a happy camper.

Members guitaristz Posted March 6, 2008 Members Share Posted March 6, 2008 I bet they would work in my next amp... http://cgi.ebay.com/YAQIN-MC-10L-Push-Pull-Stereo-Integrated-Tube-Amplifier_W0QQitemZ140212696081QQihZ004QQcategoryZ3280QQtcZphotoQQcmdZViewItemQQ_trksidZp1742.m153.l1262 Link to comment Share on other sites More sharing options...
Members JKD Posted March 6, 2008 Members Share Posted March 6, 2008 Man I was really enjoying the 77s for a while and then I put 6L6s back in there and they stayed :-/ Latest bug up my arse is KT-88s though..they seem to be everything I wanted the KT-77 to be Link to comment Share on other sites More sharing options...
Members Duesentrieb Posted March 6, 2008 Members Share Posted March 6, 2008 Hi James, how are you? Thanks for the review, I'll have to give them a try because quality is going downhill constantly (STRs) and Svets are too much $$$ for my 10^3 DIY amps.

Members guitaristz Posted March 22, 2008 Members Share Posted March 22, 2008 I suspect that if you had indiv. bias or the tubes drew roughly the same current, mixing a '77 with an 6L6, 5881, or a high biasing Groove Tube-like el34 might really deliver a rich output.A well running and perfectly toned amp seems to be a rare thing, if you know what I mean.

Members nakedzen Posted March 22, 2008 Members Share Posted March 22, 2008 I currently have Ruby EL34BSTR in her, and while I like them for the most part I do agree with your assessment that they have lots of low end but are not focused. I want a focused low end but more midrange complexity and a clear articulate top end. "Less upper mid grind",...do you think that's a good thing? In my Cobra I've liked the EL34B-STR's a lot more than the KT77's. Sure the KT77's have more low end and more headroom, but they somehow sounded flat and lifeless compared to the B-STR's.

Hard to say exactly, but the B-STR's sound more "colorful" when the KT77's sound "grey" if that makes any sense. Like there's more depth to the tone when the KT77's are a bit one-dimensional. Let's say KT77 is an image of something and the B-STR is a hologram of the same. Link to comment Share on other sites More sharing options...

Members starsnuffer Posted April 3, 2008 Members Share Posted April 3, 2008 I like the KT77's. They sound great in some amps but not all. I'm really digging them in my XTC. FYI they are also a drop in replacement for 6L6 tubes since pin 1 doesn't have to be connected to pin 8 for it to operate. The impedance matches up with a 6L6 transformer. This can really help to make some sterile "american" amps get a good british crunch without a serious financial investment. -W Link to comment Share on other sites More sharing options...
