Acquired a new-in-box Western Electric 421a (see the original padded wrapping material). I've been burning in a set of Tung-Sol 5998 / Chatham 2399 power tubes that I purchased from a follow Head-Fi'er. They are in great shape and sound nice, but when I rolled in the new Westy... ahhhhhh.....
That is one impressive looking rectifier tube sir. Congrats.

A Tung Sol 5998 for £90 is a good pick-up, if it's lightly used (i.e. tests NOS).
 
For the matched pair of E88CCs at  £190 ... I honestly didn't recall them being that much when you select matched pair. I'm not sure it matters that much, but I bought mine matched.
 
I've tried LOTS of driver tubes and these are really nice sounding (I'm listening to them now). The alternative is NOS drivers and you will spend more ... lots more for a comparable tube.
 
Just trying to be helpful ...

Yeah, I think I'll go with the 5998 and the TK's from tubedepot.
 
You've been very helpful, thank you!

Hi everyone, I got the joy of listening to a WA6SE with my Sennheiser HD700's this past weekend and am looking into purchasing a Woo Amp. I currently have a Schiit Bifrost and Valhalla 2 but am planning to pick up a pair of LCD2's.  Anyone in this thread mind making a recommendation for a Woo amp that will feed both of these headphones?
 
I was thinking either the WA7 with WA7tp or the WA2 and keep my Bifrost.  I know the WA2 is OTL, but did seem to receive good reviews with the Audeze cans.  Any suggestions would be appreciated.

  I picked up a Wa3 earlier today from Bonsey Jonsey, couldn't be happier. Sounds pretty fantastic with the stock tubes, but I'll be picking up some new ones over the next couple of week.
 
Excuse the crappy colours on the camera.
 

 


Congratulations welcome to the club !

Okay I said I would test the NU 6F8G's from the Italian supplier. All good. No issues.
 
I was able to remove the yellow paint from the top if anyone was curious. I just used finger nails.

I ended up rolling dead quiet power tubes so I could test properly (Bendix 6080 Graphite plates).
I tested the first set for 2 hours. Nada. Not a squeak that should not be there.
The second set for 1.5 hours. Same thing. Nada. That set is staying in.
 


 
Now I can return Tony's NU tubes. Thanks so much Tony. A real asset to this site.

Anyone with a WA-5 wanna comment on how it pairs with LCD-2/3?
 
I'm thinking of getting WA-5 primarily for HE-6 but if plays well with LCD series that would be nice bonus :wink:.
 
Also, how critical is the "parts upgrade" on the Woo audio site? Looks like I can only do it at time of purchase (unlike tube rolling)

I don't own however I have listened to Tony's which has very nice NOS tubes in. I was using my LCD3c's.

I also used a test track that I was familiar with plus others. The WA5 really makes the Audeze sing beautifully.
I have the WA22 with nice tubes and altho it wasn't side by side testing I believe the WA5 had the edge.

You will not be disappointed.

  By the way, on the note of adapters... If anyone is going to ask Glenn to make some adapters for the WA6, we might as well get him to make several pairs at the same time. Especially if he will make a few pairs of 6DE7 -> 6F8G adapters, which will save us all a set of adapters. Otherwise, we need 6DE7 -> 6SN7 -> 6F8G, which is 2 sets of adapters. That would be most beneficial, to just have 1 set. So Joseph, let me know if you're interested in the same thing. It would save Glenn some effort and time if he just had to make these things once. I would be willing to bet too, that he could make 10 pairs, and sell them all within a month, if people in this thread knew about it.

Have you contacted Glenn about making the adapters?  If so, I will drop him a PM to make me a set of 6DE7 -> 6F8G and a set of 6DE7 -> 6SN7 adapters.  Glenn made me a couple of 596 adapters last fall.

Has anyone used Langrex.co.uk for 6SN7 tubes and can comment on their prices/selection? Otherwise I might drop them an e-mail

Tony has. Price good. Selection not great.

They basically have a Russian tube and a Philips. Philips is a rebadged Sylvania.
