Elrog 300b's for sale. Your thoughts?


I noticed this morning an add for the new Elrogs.   I and many others on the forum ran the experiment when the Elrogs were initially launched.   We found the tubes to be superb sonically, but woefully unreliable.  In fact, the early failure rate on those tubes was apparently 100%.  I and others received replacements that were hand selected for suitability in our particular amps.  In fact one individual had 3 pairs fail.  In my case, I went so far as to purchase a PS audio power plant, having been assured that limiting incoming voltage to 115V would ensure reasonable lifetime for the Elrogs.  Two days ago, one of my replacements failed, after having been nursed along carefully.  Honestly, I doubt the tubes had 600 hours on them.  So the Psvane T1s went back in and I began the period of mourning for my deceased Elrogs.  This morning I awake to the siren song of an ad from a reputable dealer who is announcing availability of the new improved Elrogs with a 1 year warranty.   My initial reaction was, "I don't think so.  Someone else can run the $1200 experiment.  Burned once and lesson learned."  But here is the problem.  If all of Elrogs former customers take that approach, the new Elrog will also fail even if the tubes are good for 10000 hours, simply because no one will buy them.    The tubes are so good that it would be a tragedy if that happened.  So the question to all of you who have already been down this road is this?  What would it take for you to give these tubes a try again?

WE 300B 5-year warranty is based on a declining scale in which WE will provide a replacement for defective tubes based on a percentage of the current retail price.

  • Year 1 – Free of Charge
  • Year 2 – 20% of then current Retail price;
  • Year 3 – 40% of then current Retail price;
  • Year 4 – 60% of then current Retail price;
  • Year 5 – 80% of then current Retail price;

Yes, five year warranty, for real. I had to revisit their site to make sure I had it right. 
Thanks Charles. The WE re-issue tubes are very intriguing to me. The tubes will be built in their brand new, state of the art tube production facility yet using their "secret sauce " metallurgy from the 1930's. They won't be cheap at $1299/matched pair but they do come with a five year warranty. 

I'll check with Aric regarding the EML mesh plates as I'll either get them or the XLS to try while awaiting the release of the WE's. Can't have too many tunes on hand as far as I'm concerned!
Tom
Tom,
I used a loaned pair of the Sophia Electric Royal Princess  for about 3 weeks and they sounded very good in my Frankenstein.  I also had a loaned pair of the Western Electric reissue 300b about 4 years ago but didn't like them in my amplifier.  It's certainly quite possible that they could be a better match for your amplifier and you're getting a different version (presumably) of this reissued 300b. People say that the Psvane W.E.Replica is a very good sounding 300b option. 

Based on my experience I believe that certain 300b tubes sound better in some amplifiers compared to others. Tom I'm very interested in your listening impressions of the Western Electric reissues once you've heard them in your system. Tom depending on the operation points  (O.P.) of your Aric Audio amplifier the EML meshplate could be an option. 

The only drawback I note  with the upper tier 300bs is they are expensive. But I'll concede they do sound fantastic. 
Charles 
All this 300B tube talk has me wanting to try another pair. I'm currently using the Sophia Royal Princess 300B and am quite happy with them but I've not had any others to compare to. I'm currently on a waiting list for Western Electrics 80th anniversary 300B re-issue due out this September. I have no idea what they will sound like but I can't resist trying out a re-issue of such a classic. 

Good luck with your Ulfbehrts, Jcarcopo. I can't imagine you won't be very happy with them. I don't have the room size for them but I couldn't be happier with the SE's. 
@charles1dad Yes, good call sir. I’m stoked to have 3 fine pairs tubes to roll with. I’m still on the fence on getting a pair of Takatsuki, but parts connexion has them for like $1650 which isn’t bad considering the $2500msrp and the Elrog’s recent bump in price. He listed them on Audiogon a few times, I think I offered him $1450, but he said no. 😂 Now to get Eric some money for some Ulfberts. I have a local audiogoner waiting patiently for up to 2 months to buy my DIs.
Jdnrbob, Sorry, The SVIIs are Coincident Super Victory IIs and the TEIIs are Coincident Triumph Extreme IIs.  The TE IIs are monitors that are no longer manufactured.  
Hi Jcarcopo, 
I was impressed with the EML  meshplate right out of the box  I understand your positive comments,  as I said in an earlier post it's a terrific sounding tube as is the XLS.  The meshplate is finesse/nuance yet dynamic.   The XLS is dynamic yet nuanced.  I find both transparent and high resolution. 

I could see someone owning both and enjoying their individual differences which are subtle as you note but clearly noticeable. I wish I could use the meshplate in the Frankenstein.  Beautiful sound but failed in just a couple of months.  I strongly felt that you'd be happy with this tube. 
Charles 

@charles1dad I got the mesh plates today! I've got to just say they may very well end up being my new favorite.  I perceive better transparency. Micro dynamics seem to be a little more pronounced, but not artificially so.  Ambient information seems to be conveyed just better. What really seems to be noticeable is vocals are both startling explosive with dynamics and still nice and smooth.  Effortless comes to mind.  I might be trading a tad in overall dynamics, but the nuances of improvement seem to be totally worth it.  I'm listening to Allison Krauss and Junior Wells/Buddy Guy and the instrumentals seem slightly better delineated with better tonal texture and colors.  I hate to say a veil has been lifted because I hate it when reviewers say it ad nauseum, but it's as if I'm noticing an increase of subtle information that was being shadowed by the xls tubes.  So far I'm liking the changes, but regardless of the words I'm using this is still a very incremental change at best.  It's very much more similiar to the 300b xls than estranged. Startling dynamic vocals and certain instruments popping with more detail is probably the biggest takeaway with the mesh plate.  I'm not really a big believer of power tube break in as much as I'm a believer that I adjust to the tubes sound over time.  I'll monitor them and do some comparisons after the honeymoon is over and report back in a couple of weeks. 
Hi, can you tell me what speaker manufacturer are the SVII and TEII?
Google got confused.
Bob
@charles1dad  I will update you as soon as I get them.  Unfortunately my shipment is delayed with UPS. Probably weather related. The package seems to still be in NY. They claim it will be here tomorrow for delivery, but the tracking hasn't moved since Friday so I'm not holding my breath.  I really am a child waiting for Santa when it comes to audio related deliveries.  
H Jcarcopo,

If you have the time and inclination let us know your initial listening impressions of the meshplates. Regarding the speaker dilemma,  as long as you have adequate space in your listening room I believe that you can’t go wrong with either choice.
Charles
@charles1dad 10/4, I'll know sometime today once the tubes arrive.  I really can't wait my to get my Ulfberhts in a few weeks.  Still torn between the SE DIs and going all in once and for all, hope I'm making the right choice for my room. 
Jcarcopo, 
 If George is familiar with your amplifier and believes that it's appropriate for the EML meshplate I'd be confident with their use. Unless there's some unforseen synergy issues with your system I believe that you'll really like the meshplate tube. Sonically it was very fine in the Frankenstein .
Charles 
Cal3713,  I don't have any threads discussing in detail the amps I have used to drive my SV's.  Briefly, when I purchased the SVs, I had only the Coincident Frankenstein and Dynamo amps at my disposal.  Initially, I had my medium sized room set up in a long wall orientation, so that I was listening near field.  Even in that set up, it was pretty clear from the start that the Franks weren't driving the SVs well.  Plugging the SVIIs  into my existing system, which had previously used Coincident Triumph Extreme II monitors, was a disappointment.  I worked pretty hard on the room, setting it up with a short wall configuration and adding about 3K in room treatments, all of which helped, but it was clear the Franks just weren't going to get it done with reasonable listening levels.  Way too much distortion, indicating the 300Bs were being driven too hard.  A brief evaluation of the EL34 based dynamo, also rated for 8WPC, was less satisfactory than the Frankensteins.   At that point I decided to give the Atma-Sphere M-60s a try.  While they certainly don't have the classic 300B sound, I found them a much better match for the SVII speakers.  I can tell you this.  I spent the better part of a day auditioning the Frankensteins driving a pair of PREs in a smallish room near field, and the Franks seem to do just fine with every kind of music I threw at them. Now, I rarely listen to levels beyond about 95 dB peak, so things could be different in a larger room if you go louder, but as I say, I heard the PRE/Frankenstein pair for a long period and never heard a hint of distortion.   Hope this is helpful.  
@charles1dad  Thanks for the input on the EML Meshplates.  George seemed to think that I should be okay running them in my amp leaving the autobias circuit at 75ma.  I think I'll turn it down to 65ma and see how that goes.  Frankly I don't know what the operating point for the Diavolo 300B version is and the designer has not returned my email which is typical of Tom Willis if he's off doing an audio event.  I assume the lower voltage taps on my power transformer is <375v because I have 450v higher voltage taps if I want to run the Diavolo for ~13wpc with certain tubes (300BXLS, 842vhd, VV32B, etc).  I have a fluke multi meter, but honestly something really scares me about probing around high voltage for fear that my old clumsy ass will accidentally blow something probing the wrong thing or I'll slip and kill myself, lol.  
@brownsfan Do you have any threads where you discuss the amp choices for your SV's? I bought some coincident PREs and am trying to figure out how to amplify them (or whether to keep my Franks and find an alternative speaker). It sounds like maybe I'm experiencing some similar issues (I pair the Franks with super eclipse iiis).
Autospell strikes again,  in the final paragraph should be overall subtle "distinctions" not destinations. 
Hi Bill,
Thanks for the thoughtful and clear description of your 2 audio systems.
I can understand not wanting to move equipment around if it isn’t a simple task. Your summary of the 2 respective amplifiers is on the mark. I had an opportunity to hear the Frankenstein and Atma-sphere MA-1 head to head in a friend’s system who had easily driven speakers. Essentially it is 
2nd order harmonics(just a dash as you wrote) versus the 3rd order harmonics character of the MA-1.

The Frankenstein came off a bit fuller tone and harmonically richer.
The MA-1 a bit leaner and faster. Overall subtle destinations, both were exceptionally open,transparent and very lively. You have two excellent power amplifiers with their individual sonic signature.
Charles
Charles,
You ask two great questions for which I have less than clear answers.  First of all, I have not evaluated the M-60's driving the TE II's.  Getting the SVIIs dialed in upstairs was a bit of a chore, and moving them in and out of the room is a considerable project.  Similarly, optimal positioning of the TEII's upstairs would likely require a fairly significant investment of effort, without which, a valid comparison could not be drawn.  Moving the M-60's downstairs is also not going to work.  There is just not enough room for them in the area in which the downstairs system electronics resides to accommodate them.  So that experiment is pretty involved and probably won't do more than satisfy curiosity.  As for the essential differences between the two systems playing the same music, it is pretty much what you might expect.  The TEII's are the best monitors I have heard (although I can't say I've auditioned scores of monitors), and they mate superbly with the Frankensteins.  I do not perceive that the Franks struggle at all to drive the TEIIs, based on the absence of objectionable levels of distortion.  While it must be stated that the source and preamp downstairs are not in the same class as the ModWright Sony HAPZ1 and Coincident Statement Line Stage present in the upstairs system, both source and pre are good enough to convey the essential strengths of a 300B DHT based system.  That dash of euphonic 2nd order distortion, absent in the M60's, can make for mighty sweet listening.  The TEIIs driven by the Frankensteins are going to be pretty hard to beat in my book for Schubert Lieder, violin sonatas, and the like.  It is a really good "sooth the savage beast" system perfect for decompression after a day of frustration.  As you might expect, the M-60/SVII pairing has a clear  edge with larger scale works, especially when there are large swings in the dynamics.  When it is time for Mahler or German Opera, it is time to move upstairs.  Upstairs has the advantage of dedicated circuits, room treatments, and superior ancillary equipment, so this is not entirely due to differences in the two amps.  As you know, I found the Franks to be not up to the task of driving the SVII's.  No amount of effort on my part could make this work.  So I've got two respectable systems that serve me well.  Don't ask for a Sophie's Choice here.  I love both systems, and won't give up either.  I suspect that if you had both amps as options in your room and your system, you might feel the same, but might have an easier time sticking with the Franks if you had to choose one. 
George is is a honest and straightforward person.  I bough my EMLs and Elrogs from him. He firmly stood by me and provided excellent customer service during my Elrog failure episodes. 
Charles 
Jcarcopo,
I tried the EML meshplate in my Frankenstein several years ago. The operating points(O.P.) in this amplifier are too demanding for this more delicate 300b and so durability is poor. If a 300b amplifier is gentle in terms of O.P. then the meshplate tube is a very viable option. I will tell you that the EML meshplate is absolutely beautiful sounding.

A bit less dynamic than the XLS but very airy with much finesse. A different sonic perspective from its EML sibbling. If I had the appropriate amplifier I could be exceptionally happy with both of these. The XLS is an ultra built, robust 300b that sounds superb. A wonderful fit with the my Frankenstein SET yielding a powerful, tactile and very natural sonic character.
Charles
@charles1dad  I guess I'll find out if the meshplates are an improvement.  I just ordered a pair from George at TubeUSA.
@charles1dad   I'm ecstatic that people are getting such longevity out of the EML tubes.  I want to possibly try their 300B Meshplate, any thoughts?

@brownsfan You're quite welcome. Yeah I can't see spending that much on another pair for the subtle differences that I'm hearing, but I do like rolling between them and EML just for the change of pace.  It's nice to have choices.
Bill,
Well you do have 2 very fine audio systems to enjoy when some struggle to develop just one. Of course you know how I value your listening impressions and perspectives. What are the essential differences (If any) you hear between the 2 systems playing the same music. I realize that one uses full range speakers (Super Victory) and the other monitors on stands (Triumph Extreme). If must be quite nice to have both a first rate SET mono blocks and OTL mono block amplifiers for enjoying your classical music library. Have you tried the M 60s with the Triumph Extremes?
Charles
Charles, I'm sure the EML is going to be just fine.  Its been a year since my 2nd set of Elrogs burned out.  That should be enough time that a comparison of the Elrogs and EMLs from me will be meaningless.   Over the years I've learned that we seem to hear the same things, and value the same things, so I have no inclination to run a very expensive experiment to ensure that that still holds true.   I do think that the Elrog design offers much to recommend itself, and I want them to succeed and continue to roll out new products.   But, they got off to a rough start, and I suspect they are going to have to offer something better than diminishing returns at premium prices to fully realize their potential as a company.   BTW, I am really enjoying the Franks in the downstairs system.   Nice having the luxury of a good SET system and a good OTL system based on the M-60's.  
Hi Bill,
It good see a post from you, it reminds me of the of the good old days on this forum 😊. To be fair you just might find the Elrog superior and may prefer it based on your own comparison. The Elrog certainly is a excellent sounding tube with its undeniable strengths. You could find the gap between the Elrog and EML XLS perhaps a bit wider than jcarcopo or myself.

As I wrote above when all is considered sonically across the full spectrum the XLS does acquit itself very well.Bill some say that the Psvane W.E Replica 300b is an excellent tube and probably a bit more organic and midrange centric relative to the EML XLS.

I don’t envision Elrog (or any tube manufacturer) producing a surplus of their tubes and dumping them here at ultra low cost, so I believe we’re safe from tariffs 😊😊.
Charles
Jacarcopo,  Thanks for posting this report.  I've exercised considerable discipline in waiting things out for a year before making a decision on Elrog vs EML XLS to replace my Psvane Ts.   Much as I loved my Elrogs, I just can't get to a justification for taking that risk again, and even if the reliability issue has been solved, I'm not hearing either you or Charles reporting a huge separation in purely sonic terms.  Hopefully, I'll get around to this before a tariff on vacuum tubes is imposed. ;>)
Hi jacarcopo,
I glad to hear that the current Elrogs are seemingly more durable compared to the earlier versions I had. Despite our different Amplifiers/audio systems I find our listening impressions virtually identical. Yes I’d say that the Elrog is just a little bit smoother, warmer and organic in presentation. The EML XLS is more dynamic and authoritative yet retains an organic character  and is by no means a "cool" sonic presentation IMO.

The XLS is as you note very robust and well built. There are reports that early versions of this tube are approaching 40,000 hours of use and yet still are able to test as new. By any standard this is impressive! I did enjoy the Elrog in my Coincident Frankenstein amplifier but honestly I don’t feel as though I’ve lost anything with the EML XLS (Just subtle differences and tradeoffs) . At this juncture I’m very pleased with them and don’t anticipate a tube change.

The XLS isn’t inexpensive itself but does offer excellent sound quality and apparently extraordinary lifespan/ reliability. After over 3 years of heavy near daily use mine tested exactly the same as the day I got them.
Charles
I just passed the 1 year mark for my Elrog 300B tubes. I will admit that I have also been running the EML 300BXLS in my Art Audio Diavolo 300b SET Copper Reference amplifier as well. So I can say they have about 1000 hours on the Elrogs. Regarding sound quality, I enjoy both tubes equally and wouldn’t say one is particularly better, but the Elrog is a tad smoother, slightly more euphonic, and a tad less dynamic. EML 300bxls comes across as more dynamic and neutral sounding to my ears in comparison. I’m splitting hairs here as they both sound much more alike than different which surprises me as they are constructed differently. They are both superbly made tubes with excellent construction and looks, but the EML 300bxls are structurally built more robustly and are beefier in looks and stature whereas the Elrog feels a bit more delicate, but the Elrog probably would win a beauty content based on looks and that beautiful glow that you won’t get from the EML.

The real question is would I buy them again. Well, at their current prices ($1455), which is more than I paid a year ago, I will not be reinvesting in them because they have priced themselves out of the market imho. They simply aren’t worth the premium for that subtle of a difference. The EMLs have a much better warranty, proven reliability, and a much more affordable price point at around ~$900. More importantly, and correct me if I am wrong, but running a 300bxls at 8wpc should probably last significantly longer than a normal 300b as it’s designed to put out more wattage and they are basically loafing in my amp’s standard 350v/75ma voltage mode. If I flick a switch I installed into my amplifier it switches to the higher 450v voltage transformer windings. I then just tweak the auto-bias circuit pots from 75ma to 110ma & I get about 13wpc which is an added bonus and a very noticeable improvement in performance for certain types of large scale music that the higher wpc output setting does benefit from.


Interesting remarks from Thomas about 300b operational points, I remeber his amp showing 140mA at the milliamper meter (400V at voltage meter), is that a sum of current for two tubes?
I have interest in purchasing the Elrog 300Bs. Have there been any other experiences since the last glowing post by diminishing_returns who surprisingly has that one and only post on audiogon? Have the reliability issues been ironed out - any user experiences to share?
Hi!

I hope to have the website updated by end of the month. We are totally busy with production catching up with demand and development of a new tube type to be launched at the High End fair in Munich in May. So the web site had to wait. But there are regular updates on my blog and I will keep posting about the tubes and manufacturing process. See here:

Hi!


Thanks a lot for your feedback and sound description. T-shirts will be made  :-)
We will have them for the High End show in Munich this May. Anybody who plans to visit the Munich show, you can visit us in room F231e


Best regards

Thomas
I have had Thomas's new 300b's in my Manley Neo Classic Pre for over a month now.  Within one day of listening to them I ordered another pair.  I can't say enough about Thomas's help and Mr/ Lenz's great customer service. I can also say these tubes don't need any real break in period compared to the others that I have used. I own many -both chinese we300b 1:1 models (psvane and shungyang), Gold Lion 300b, EML, Western Electric 300b (68), Takatsuki TA-300B.

I replaced my Takatsuki TA-300B's and I prefer the sound of the Elrog 300b by a . Now theTakatsuki is a great sounding tube and was my favorite until the Elrog ..yes including the original Western Electrics.  

IMO the Elrog is not yet another 300b clone.  This tube is very different and sounds more modern and defiantly less pillowy on the bottom end.  Transients are much faster and in genera the tube is a joy to listen to.

Thomas, thank you for acquiring Elrog and making the changes you have.  I hope to have you build me a new archiving pre for my turntables that bests the Manley Steelhead I am using now. Also, can you start making some Elrog t-shirts already? 


(yes I am now an Elrog fanboy)








Hi!

We have several customers with Lampizator DACs who use the 300B after the major improvement in the filaments in January 2016. None of them have reported any issues. The tubes should be operated like any other 300B. Especially the 45 has a much lower filament voltage than a 300B. So use the 300B setting of your DAC

best regards

Thomas
I have been considering the Elrog 300b's for my Lampizator Golden Gate Dac but have held off because of all the failures reported by the Lampizator community. Mikelavigne reported success using the 101d,45 setting instead of the proper 300b setting. I wonder what would be the proper setting to use with the new and improved Elrogs. 
Based upon the threads, even on Audiogon, relative to poor experiences with the prior 845 regardless of  whatever  the causes were and the apparent lack of current manufacturing empirical data , I'm having a hard time at this juncture to move forward at the  $1650/pair price tag
Facing one's critics and being honest and forthcoming is an excellent start in rehabilating one's reputation.  I wish only the best for Thomas and Elrog
Hi!

For the US and Canada please send inquiries to George Lenz of tubesusa.com.

I will update the elrog.com website in January with prices and order information. Until then drop me an email


Best regards

Thomas
Thomas-

Is the website for the Elrog's up to date with prices and able to take orders or does one need to email you personally?
Hi!

As mentioned above the 211 and 845 did not have the issues which the 300B had. They suffered from the poor quality control as well. During the time I was distributor for Elrog I got only very few returns of 845 tubes.

Life time cannot be generally estimated since it depends a lot on the operating conditions. During the many problems with the 300B we learned that there are a lot of amps which push tubes too hard. This can shorten the life time. op point, usage pattern (on off cycling) and tube rolling all affect lifetime. Normally you should be able to expect 3000-4000 hrs from a thoriated tungsten power tube. This can drop significantly if the tube is abused. It can also extend well beyond that number if the tubes are handled well. The distribution is a kind of bell curve

We also do not make the 845 long enough under the new company to have significant statistical data. I do not expect any issues with the 845 though.

Like the 300B the 845 and 211 carry a full year warranty now.

Best regards

Thomas
vinylsavor - Thomas,

In purely general terms may I ask what one might expect in terms of hours of life for your "new" 845 tubes?  Some online forums suggested the prior manufacturing of those were problematic as well. Txs
Hi Al,

yes you are right, each parameter on it's own is within the allowed limits, but the combination of 450V/90mA results in a plate dissipation slightly above the maximum allowed 40W. 450V * 0.09A = 40.5W (40W max)

Best regards

Thomas
Thomas, thanks very much for your excellent responses.  And I second the good wishes extended by the others.

Regarding:
450V/90mA would already be slightly over the limit and thus is not recommended.
I would add that neither number is in itself over the limit.   It is the combination of the two that would result in the tube's maximum power dissipation rating being slightly exceeded.

I say that based on the ratings indicated in this datasheet for the original version of the Elrog tube, as well as on the ratings specified in this 1939 datasheet for the original Western Electric tube.  Although this 1950 datasheet does indicate 400 volts as a "maximum rating, design center value" for the Western Electric tube.

Regards,
-- Al  

All,

thanks a lot for the positive responses and good wishes. As mentioned in my post so far there was a single beta tester who used the tubes in a Frankenstein amp. He had them for almost half a year now. I wanted to have this test first before releasing the tubes for the Frankenstein. Since this release only happened now, there are no additional users of Frank amps yet who have the new Elrog tubes.

@jetrexpo: The choice of operating point depends more on the amp design than on the tube. As long as all max limits are not exceeded any op point which is preferred by the amp designer is ok. 450V/90mA would already be slightly over the limit and thus is not recommended. I personally use fairly traditional op points of about 350V/65-75mA

@brownsfan: The inrush current issue was solely relevant for the filament supplies. When the tube filaments are cold they are basically a short. If the filament supply uses brute force voltage regulation it will push a lot of initial current into them. An external softstart will probably not do much there. We also saw that some current regulated filament supply kits for DIY amps actually start with a current spike and initially put 7V across the filaments before settling to 5V. This is not healthy for any 300B, but it simply killed the early Elrog 300Bs. Also a tube rectified B+ supply doe snot have any affect on slowing the filament inrush current. But as mentioned the tubes are more robust now to be able to withstand some abuse at turn on. Yet a well designed amp with good filament supply and conservative op points will ensure a longer tube life. Not only for Elrog 300Bs but for any brand.

Best regards

Thomas
