I paid mine $23 NOS a piece a few months back

I sold off my 2399s, (2 pairs), and kept my 7236 power tubes. Nothing wrong with the 2399s, I just prefer the Sylvanias as they sound better to me through a wider variety of headphones.

 
Right, I just remembered I bought a pair 2399 from you. Very happy with it actually. and now I'm getting you the 596. Small world!
 
Any other suggestions in stead of the Siemens E88CC driver ($55/piece)? How about the Sylvania 7308? I can get them fairly cheap ($40)

By chance, can you source (cheaply 

 ) the Western Electric 421A (pair) from over that way?

I been. Through This debate before. untill one Seattle meet. There was member had BG installed in his woo amp also topped with Sophia. That sound was too Thick And woody on top of the already warm woody woo house sound. It was turn off for me.

 
do you recall what amp it is?  i do not recall thick and woody on wa22, maybe it is the tubes has a lot to do with it?

I was lucky back then to get a single one at $30 new in box. But I paid most mine at $100~$150 a pair back then. I managed to break one of my GEC round brown base. one getter broke off for no reason.

 

[Seamaster]

That why WA22 is just right, I did not want to mess up the house sound. Woo amps are known for warm sound.

Well, I did some tests and the result is... I don't like this tube
 
My WA3 was sounding amazing with its stock tubes, so in an attempt to make it even better I changed the power tube to 5998 and what I got was a thinner, weaker sound... kind of like my Icon HDP. Does it mean a more solid state sound? I don't know, I can't describe sound with words like most audiophiles do.
 
I didn't even take the headphones off my head to be sure it wasn't any fitting issue...
 
The worst thing  is I had to buy a pair... I guess I'm gonna keep testing and give the other tube a try too...
 
(I have plans to buy a WA22 in the future, maybe they're a better match for this amp... I hope so)

If they are NOS give them 24-48 hours, the sound will change pretty dramatically.  The other possibility is that you were sold weak, used up tubes that were tested incorrectly.  This is becoming more common as this tube becomes rare.

I have the WA3 and have quite a bit of experience with the 5998.  In general, the 5998 is more thin sounding compared to the run of the mill 6080 tubes and the run of the mill 6AS7 (G and GA) tubes.  It's strength is in bass extension, impact, and speed.  Paired with some driver tubes, it can sound on the cold side. 
 
What driver tubes are you running?  This does make a difference.  Also, the suggestion to let it run in is correct.  It takes some time for it to open up and get some tube bloom.  But, if your stock WA3 tube is the 6080, the 5998 will sound less full and warm in comparison.

Ah, yes, sometimes I forget the 5998 gets run in a 6AS7 circuit by most other people.  It doesn't sound thin when you drive it correctly. 

  To me 6080 sound thin, there is no foundation for the music.  Thin and flat.

Is there anyone want to sell WEE?

Umm...you must share your source of Siemens E88CC tubes....normally a good pair go for $250-275ish.

Personally I like the Siemens E288CC and Amperex 6922 PQ tubes. Both rather expensive but great tubes, the Amperex in particular is very sweet. Another interesting alternative would be the PCC88 / 7DJ8 tubes. I read a lot good stuff about Mullard CV2492, but never tried them myself.
