I just had a really interesting experience with the new EML.  Never saw this before, and maybe it always did this.  Here is what happens.  The filliment will get brighter or dimmer based on the position of the volume control.  The louder I turn up the volume, the brighter the filliment gets.
 
I don't notice that behavior on the other tubes.
 
The other thing I notice is that after a piece of music stops and during the pause between the start of the next piece of music, the filliment also dims to almost nothing.
 
Anyone know why that would be?

How much brighter are you talking about?  I don't think I've ever noticed anything like that with my Woo3.

I'm going to have Jack add a preamp section with balanced outputs on the rear my WA22 so I can listen through my speakers.  It can be done now through the headphone jacks, but it's not really that good.  The whole speaker thing is probably best done through the WA5 which is designed for that.  But, sometimes I would rather have some music in my office over speakers. 
 
I find that headphone music pulls my attention and it is a little harder to think critically when solving technical problems.  But, if the music is low over speakers, it can be more of a background thing.  So, I'm going in that direction.  It is going to cost a little north of $200, but I think it's worth it.
 
Just now that I have my new EML in and all tubes are finally settled down and broken in (almost I only have 28 hours on the EML but it's sounding sweet as honey), I so don't want to send anything out.  Maybe I'll wait a month or so before I send it in for the mods.

I'm assuming powered monitors, what kind?

3 day delivery on the wa2!  Wow, thats great.  I waited over a month for mine.  This is the way it should be.  Places that are making people wait 2 years for amps should go to Jack for productivity lessons!

Well, the economy is on a slight upturn, hopefully; perhaps they're building a few of the popular models ahead of time, or at least partially building them.

will likely start with the EML5U4G rectifier, the Schuang Treasures for the drivers and GEC6AS7G for the powers. And Ill go from there.

 

No offense intended, but I had to chuckle at that last bit for a second.   
 
If you start with that there arguably isn't anywhere else to go from there.  You can interchange the treasures with the Tung Sol round plate, otherwise you just named what are widely held to be the best sounding tubes the WA22 can be outfitted with.  If you aren't into tube rolling for the experience of it then you have a fine plan in place, otherwise I think it might be more rewarding to try a more modest tube combination first and then "graduate" to the best.  At least while the amp is breaking in.

Double post.  The forum servers really seem to be struggling lately.
 
edit: *blinks* wow and then it turned the post I was editing into a completely new third one.

hey Mike, just wanted to tell you how much i LOVE the PREAMP function (on my WA2).
i've got audioengine2's hooked up to it.
 
after months of getting used to it, i can't listen to my A2's without the warm/thick/3d sound of the WOO.

I have never experienced this with any prior EML's or any of the many rectifier tubes I have used over the years for that matter. 
 
I would contact Jack to see what his take is on this, the new current " fourth revision" of the EML 5U4G is supposed to make it a more rugged and reliable tube but regardless of the great sound I can't see this being normal behavior. 
 
Please keep us posted Mike on any info. 
 
Thanks!

At two clicks from 0, the filliment is thin and blends somewhat with the screen.  When I go louder, say 4 or 5 clicks from 0, then the filliment gets brighter so I can see the entire structure of it.  When the music pauses, then the filliment brightness fades considerably to a point that is similiar to when the volume is at two clicks.  When the music starts again the volume stays the same, but then the filliment slowly gets brighter.

Well, I'm feeding my Audio Research VT100 amplifier.  It has balanced inputs and I am driving a pair of Vandersteen speakers.

What Jack is going to do is wire my WA22 up so it can feed an amplifier that will drive a pair of speakers.  However, after reading your post, you got me thinking, maybe I should ask if I could simply get a pair of speaker binding posts and directly drive a pair of speakers.   I'm going to email him tonight, thanks!

just got my quad of TUNG SOL 5998's in the mail (paid $150 on ebay)
 
plugged two of em in my WA2 and so far i am realllllyyyyy enjoying the sound...
 
 
it's like the "room" got bigger... there's more space/air.
 
i know i'm not saying anything NEW, but it feels good to FINALLY hear
what all the TUNG SOL 5998 fuss was about!

 The Wireworld cables have less resiantance than other cables that's why you have to reduce the level. I switched to Eclipse 6 in my system and really like them. The Zeus headphone cables are made of the same OCC Wireworld cables inside the Eclipse 6.
 

Glad to hear you like the WW interconnects, I should have mine later today.
 
The HE-6 cable is also the same OCC, Peter sent me this picture last night when he finished making it the way I asked him to. I wanted the cup cable ends to be as short as possible so not to hit my shoulders when I am in my recliner along with flexibility and as lite as possible.

Dear Silly,
 
I am not having any problems, past or present with my tubes and I am a little shocked that you are bringing that up since the system administrator deleted your posts on the tubes issues.  I am also not having any problems with my WA22 either, and I don't understand how you came to that conclusion.
 
I have been very clear on this.  As I have written before, and I will write it yet again; Jack Woo said to use the 110 voltage setting out of my P600. You are the one who has posted not to use 110 in your answer to Xcalibur255, "You really don't want to limit your voltage to 110V, if you live in the USA."
 
 

Please chill out. I am glad you think your power setup is right for you, that's great.
 
Please understand that it's not me saying this it's the USA Government pointing this out, so please don't take this personal as its not coming from me. However you may want to take this up with the USA Government and get them to change there guidelines.
I think you may want to add to your post that the "system administrator" deleted your posts on this particular set of tubes also. Also please understand that I did not use bold text and underline in my post that you are quoiting me from. That kind of text and underline can be considered as aggressive and argumentative and that was not and is not my intent.
 
Anyway i have PM you as was suggested by the "system administrator" (Jude I am not calling you system administrator) in hopes of helping you.
btw, did you try and plug your amp into a wall outlet and see if the glowing oddity goes away.
 
Peace.

You forget the Brimar CV1988, IMHO, it is better than the Treasures.  He must have some good contact to get the GEC 6AS7G, I have been trying to get another pair for a long while and unable to find a perfect NOS pair.
