I have just put my Jolida JD-1000P back into my system, and when I initially fired it up one of the tubes was obviously bad giving a good light show. I found this kind of strange as the amp has been sitting idle with no power to it for about six months now and the tubes Winged C Svetlanas were working fine when I took it out of the system. I replaced the winged C with another Svetlana for now and ordered up 8 matched Tungsol re-issues as I have heard that these tubes are some of the better of the re-issue tubes out now, what are everyones thoughts on current re-issue EL-34 tube available now.
Ok, I have the Tungsol EL-34s in the amp and they really do sound very good. Now for the crazy part, I moved up the Jolida chain to the Music Envoy 200 watt monoblocks, I couldn't pass up the deal I got on them. They use EL-34 tubes in the driver position so I invested in a quad of Gold Lion KT-77 tubes for the new amps and they sound superb. So now to sell the 1000P to offset the cost of the new amps a little. Thanks for all the comments guys.
Mesa sells more affordable Russian and Chinese tubes. But if you look on their web site you'll see a specific description of STR450 being limited quantity NOS Seimens, and they are, but those tubes are NOT stock in any Mesa amp.
I would agree with Rich - I also am currently using the EH EL34's in my PrimaLuna amp, and they sounded better than both the stock tubes and the current issue Mullards that I tried.
I stand corrected Phil it was not the NOS Siemens tubes I had in that amp, it was the otherEL-34 tubes from Mesa. That is actually a pretty good price on those NOS 34s on their site.
I owned a Mesa Baron amp, it is the one piece of equipment that I regret ever selling. It had the tri tube factory upgrade. I had a set of those EL-34 tubes in it and wasn't very impressed with them at all, are you sure those are Siemens tubes? Now I have also heard that the Shuguang Treasure tubes sound real good.
Hi Viridian, yes that is true of the 6P3S-E but depending on how high the impedance is in the circuitry of the amp they can be used, they actually draw less filament current than an EL-34 which should make them a little easier on the amp. I've been reading Michael Samra's findings with this tube in EL-34 amps over on AA. If the impedance is on the lower side the tubes may be a mismatch.
If you ever hear true NOS Siemens or Telefunken, or Mullard EL34s, or for that matter NOS GE 6CA7s, you'll understand how woefully disappointing are the current faux "Tung-Sol", "Mullard" and various other iterations of this tube coming out of Russia. There are two excellent commercially-available alternatives:
1/ Shuguang Treasure 6CA7 - this sounds closest to the great vintage EL34s of anything in current production.
2/ Mesa Boogie, the guitar amplifier company, still has robustly-tested NOS Siemens EL34 in matched pairs for sale on their web site (go to the Store link). They are relableled Mesa, are genuine, and aren't going to last in their inventory indefinitely, so don't lollygag if you want them. They're worth it.
Viridian, I am going to try the 6P3S-E tubes for sure, at their price it is almost a no brainer. I have seen some people that say they may be the best sounding of all the current EL-34 tubes available.
There is a guy on eBay (bnsanborn), that sell tubes. I bought a quad set of Seimen EL34's for $190 about a year ago. They are much better than my Winged (C)'s. I just bought a back up quad set from him eventho I have 3 quad sets of the SED,s. Great tubes!
Looks like I'll be ordering a set of the EH tubes as well. I agree with Rich here too, there is no way I am going to spend that kind of money on power tubes, they do not last a life time at all. Maybe if I had a mega buck system I would consider it but I don't and I won't. I have spent some coin on the driver tubes, they will last much longer than the power tubes, I am currently using Telefunken NOS 12ax7s there and real happy with the results. Sounds like the genelex KT-77 have a good following too.
I second the (reissue) Genelex KT-77s. Mine replaced "Holy Grail" Mullard xf1 EL34s (I also have xf2 and xf4 Mullards) as driver tubes in a pair of 845 SET monoblocks. Surprised the hell out of me. I've also tried JJ KT-77s but they're not up to the standard of the Genelex, IMO.
I also have 2 quads of EH 6CA7 tubes in my JWN amplifier, and they sound very good. No problems so far. Bought them based on Jim McShane's recommendation. He says they are a close second to the Gold Lion KT-77's, and much cheaper.
Interestingly enough, going with NOS power tubes is almost like having mods done on a unit. The cost for a quartet of NOS Mullards can be a 1/3 to a 1/2 of the cost of the amp and it is debatable if the effect on the sound is worth that much. Power tubes do not last a lifetime ... preamp tubes maybe, but I have had NOS preamp tubes crap out after a few years.
I hate to say this but forget current production.... If you really want to know what an EL34 is all about get yourself some new old stock (NOS) Mullard xf2's or xf3's. They'll smoke you and last a lifetime.
Rich, I totally agree with the warm up aspect, I too give the amp and preamp 30 minutes of warm up time before playing any music. I'll have to revisit the EH tubes, and Stevecham, I too like the tube depot, thats where I have ordered the Tungsols from.
The secret to tube life ... which I learned 45 plus years ago with my dad in his TV repair shop ... allow enough time for the tubes to warm up. I allow for at least a half hour. Even though the Prima Lunas have circuitry to allow for play after 30 seconds, I find that the tubes last longer and are pretty noise free, when I just let them warm up. I am getting good hours on the EH ... can't say whether it's a 1000 hours or more, but I have not had to replace them in at least a year or so. The EH cost is also very reasonable ... about $20 a tube, so it's not that big a deal.
Thanks for the responses so far keep them coming. I have tried the Mullard reissues and did not find them as well rounded as the winged "C" tubes. Rich how have you found the EH tubes as far as reliability, I had some problems with those a while back, maybe they have improved? I may just end up trying a few different brands to compare, the JJ KT-77 tubes interest me also. I do realize this is all system dependent but I appreciate all comments.
I second the EH EL34 and recently retubed my CJ amp with these. Great, depth, warmth and richness of sound, very sweet and detailed. I have no desire to change these out for others. And no fireworks. I STONGLY suggest buying from Tube Depot; they have always sold me quality tubes that test well and last a long time. A great company.
I really like the sound of Electro-Harmonix EL 34 and 6CA7, which I use in both of my Prima Luna amps. Prefer them to the Winged C's. The EHs have good detail and richness in sound.
How about Genelex Gold Lion KT-77's ? I replaced Svetlana EL-34's with a matched quad of these, and the music sounds really, really nice. The KT-77 is a mighty fine tube.
The Winged "C" is musical and lush, with plenty of liquid. So far all of the offerings I tried from New Sensor seem to lean toward a dry, and almost sterile sound. The last new stock Tungsol still seams to have their (New Sensor) house sound, maybe a little more detail than the SED. Their sound still reminds me of their Sovtek line. The SED (Winged "C") seems to have more problems again. This is my experience.
