WA22 let's roll some tubes (Done Mod, Burnning-in)

 Using them with the Brimar 5Z4GY and stock drivers definitely fills out the bottom end correctly, but I feel like the openness heard with the stock power tubes is sacrificed slightly. 

 
One of my favourite combo is 5998s with 6su7gty and Western Electric 422a as rectifier.  Beautiful analogue sound with holographic soundstage. Substitute 6BL7 for the 5998 and then I get a more fast clean sound much like Solid state (V200).  I am using a Metrum Musette DAC btw.

What version 6SU7GTY? Tung-Sol?

Yesss. I'm renting out my loft for San Diego Comic Con weekend in July and using the extra cash to get that WE 422a. A few nights crashing at my buddy's house(with his insane 11.2 home theater)and I'll be right on target to pick up that tube and some Shure SE846 IEMs without touching the piggy bank. Score!

I would suggest not paying more than $400 for the WE422a. And if you can, pick up some 6BL7 too.  These are cheap as chips.

I tried a pair of NOS TS 6C8G this week. I haven't had too much luck with these types of tubes in the past, but this set is really nice. They have a certain warmth to them that I haven't found in most other tubes. I know describing a tube as "warm" might seem a little odd, but that was my immediate thought when I listened to them. Thanks to @Badas to making me go hunting for another set.

I've just taken delivery of another set of those plus others. I think I agree and would say they are the nicest. Not by a lot tho.

I've been comparing NU to TS this week. All week I've had the NU in and have now rolled the TS. The sound is extremely similar. I can't say one is better than the other. NU has a little bit sweeter treble. TS seems a little more natural.

I will point out tho. The NU is one friggin fussy bloody tube. It doesn't like a lot of power tubes. Don't even try with 6BL7. Total noise mess. Both 6F and 6C is the same. I did find it behaves with GE6AS7GA and the Mullard 6080. Not a lot of others tho. The TS was stable and behaved with everything.

I just picked up a 6 month old set of SE846 IEM's from a local audio buy/sell site. Very nice!

As others have mentioned the 6BL7's work very well in the WA22. I have rebranded Sylvania and also GE quads. I posted further thoughts and pics on the 6BL7 thread.

Funny you should mention. I did this last night.
 
Finally got around to running 2 6BL7 tubes off the single 6080 power tube circuit on the WA22. Using the adjustable position adapter. I was hoping the adapter had enough scope to have the tubes in line. It does.
 
Haven't listen too much yet (a few hours). Very clean, no noise and the transformers don't get hot. I did notice a big bass jump. Amazing how much bass the WA22 can throw out. I will evaluate over the next few weeks.
 
It is a tight fit but everything does fit.

No concern with using different construction types for the 6BL7's? Took me a little while to find matching quads, but wasn't too difficult (for now...)

No concerns. I actually wanted different types. I want to mix it all up to get different flavors. I have 1 of each of the Sylvania made tube and 1 of each RCA in each socket at the moment.
 
Soon I want to put in the Sylvania X plate and flat plate together in each socket. That should sound good.
