At any time did the fuse get blown? Probably not, otherwise you would have mentioned it.
 
 

 You are correct.

On a performance note, did you drop in a HiFi Tuning Supreme or Furutech in that bad boy?

You are right, too.

 I have a HiFi Tuning Supreme fuse replaced in same current in slow blow.

Hi Danny,
 
Sorry to hear this my friend.
 
Tell Jac what's happened to the EML he might be able to replace it FOC.
He's a very nice person.

hey dannie, have you checked the bad tubes to see what is wrong with them? using a tube tester may let you know what may've happened. the blue spark is arcing, which is not what should be happening to a good tube. try other rectifiers to see if the arcing is constant. if so, the power supply may be in need of servicing.

Danny,  so sorry to heard both your tubes went bad.  Is it possible the ECC32 cause the EML went south?  It is very strange both the driver and rectifier die at the same time.  The EAT are fine?  I will take them out for a while to make sure is not the amp.

Got a Furutech in the Woo. And a 'Supreme' going into the W4S DAC-1 soon...

Hi All,
 
We have just made an announcement for a new flagship amp. Please check the Sponsor Announcement thread.
 
The new 24/192k DAC and top loading CD transport will also be released at the same time.
 
Cheers,
Jack
 
 

Jack, will any of the design and technology advances in the new amp trickle down to other existing products in the line in the future?

Wow, that's a shame to hear about your EML tubes dannie.  It's just too suspicious for both of them to go at the exact same time though, there must be an abnormal operating condition somewhere.  The fact that the tubes you put in just afterwards were arcing only makes it more suspicious.  The NOS tubes seem to be made of "tougher stuff" so we apparently never get to see an EML tube arc, it just dies.

Looks like a great concept but I have to be honest If I'm going to spend $10K I'm going back to the the realm of high end speakers.  The headphone experience just doesn't have the innate magic to warrant such an expense, whereas $10K spent in the high end speaker world will bring an unmatched magical return.  This is not to say the amps are not worth $10K.  It's just that we are talking about headphone sonics and one does have to suspend a certain sonic sensibility to accustom oneself to it's realm.

Checked with Jack and he said the umbilical cable could go up to 48" without performance loss.  I'm just about ready to pull the trigger on a WA5-LE with the parts upgrade.  Still haven't decided on the tubes yet though.  Couple of questions if you guys could help, have tried searching but some of these threads are just massive.
 
1.  Is the general consensus that you can't go wrong with any combination of the EML or Sophia Princess tubes?
2.  How are the Shuguang Treasures?  Jack mentioned he had Black Glass tubes that outperformed the EML 300B at a cheaper price point, assuming he meant the Shuguangs.
3.  Any recommendations for the driver tubes?

The stock cable should be around 12" in length, better confirm with Jack and you can always ask him for an offer of a longer one. He is responsive and would answer your question always in a short period (at least I experienced). BTW, I don't think there's audible different with a longer length of the umbilical cord  let say double of it's stock length.

Beside the Mullard ECC32, I have another pair of EML 5U4G Mesh Plate that will be framed in a good looking wood frame hang in my wall for decoration. 

 
BTW, beside EML, does anyone could recommend something good NOS, thanks.

Sorry to read this.
 
Here are the specs differences, this may be the problem any why I never get away from using non drop in nos tubes.

1. [size=x-small]ECC32 Filament Current .95 Amp versus .6 Amp for the 6SN7GTB
   [/size]
2. [size=x-small]ECC32 Mu (Amplification Factor) of 32 versus 20 for the 6SN7GTB
   [/size]

[size=x-small]ECC32 Plate Voltage is 300V MAX versus 450V MAX for the 6SN7GT [/size]

 
I had the same problem with one of my EML 5U4G's going bad, and the same results except my TSRP's didn't blow. Replaced both the EML 5U4G's with a new pair I got from George and sent the bad EML 5U4G back to Jack for a free replacement. After that I have not had any problems. Plus imo I don't like the fact that the ECC32 or any drive tubes with the same shape are so close to the 300B's.
 
imo the LCD2's and HE6's put a heavy load on the PSU and AMP and if you are not careful the AMP can become very hot if the room temp goes up and or you don't have very good air movement.
I would think the last thing you want to do is send 90lbs of amp/psu/boxes back to Jack for repairs. Anyway that is one of the reasons why I went with a Liquid Fire amp (15lbs) and now have my WA5LE in storage. Plus the fact that my system is geared toward SE and I find the LF to be as well balanced as any balanced amp. I am not saying the the LF is that much better than my WA5LE (with my tubes) using my HE6's, but it is just so much easier to use and a lot cheaper to tube roll plus it has a two year warranty and just 15lbs and one box if it ever needs repairs. Plus I like the RCore transformer that is used in the LF, very low noise floor.

Yes you are right but you forgot one thing and that is room acoustics, so the same thing can be said about speakers.

Well I can pretty much take any room and adjust the acoustics, that's not a problem for me, Ive done it many times, and I can also take the near $4K I've spent on my head phone rig and compile a speaker rig that would simply humiliate the headphone rig and that price would include money spent on room acoustics.  But my current family logistics requires I use headphones instead. Headphones are a very limited medium and it take a real adjustment to accept their sonics.   It's been quite an adjustment, really a sonic and perceptive downgrade that required I stay away from speakers altogether for an extended period to adjust to the realm of headphone reproduction.  

The current headphone scene reminds me of what happened in the very late 80's and early 90's when the golden age of high end audio succumbed to the every increasing price of anything designed began to sky rocket past the affordable and out of the realm of the average audiophile.   Most of this price design was fueled by the designer ego wars that consumed the market thereafter and is still prevalent today.  This is what is happening today in the headphone realm.

Wow you are magician  if you can "pretty much take any room and adjust the acoustics" using a MCH speaker system. I sure can't do that, just changing the room size would be amazing trick.
 
I think you need to look at a different headphone rig and if you did I am sure you wouldn't make this statement"$4K I've spent on my head phone rig and compile a speaker rig that would simply humiliate the headphone rig and that price would include money spent on room acoustics" particularly if you are getting into MCH audio as I do using my headphone rig for MCH audio, but yes it would cost more that 4K.

But yes just like anything if you want to play you have to pay, no use complaining about inflation that is not going to change anything.
