Woo WA2 Tube Rolling Recommendations
Mar 10, 2014 at 9:08 PM Post #301 of 1,192
Just got my WA2 less than a week ago and am loving it with my Beyerdynamic T1's.  Am running Tung Sol 5998's, Philips Sittard EZ80's and have tried a series of very nice 6922 variants.  My  favorite has been Philips Miniwatt E188CC's.  I've tried Siemens Cca A-Frames from the 70's and a pair of 60's S&H E88CC Gray Shields.  Both Siemens pairs seem a little recessed in the mids and just a touch edgier in the treble region than I'd like.  The Miniwatt E188CC's are beautiful across the spectrum.  Wondered if anyone with T1's has a suggestion for a warmer or 'tubier' sounding 6922 for variety.  Maybe some Mullard pair or other possibilities.  I'd welcome any recommendations. 
Thanks and it's great to be on board with you Woo fans.

Would like people's thoughts on comparing
the Western Electric 421A vs the GEC 6AS7G...especially as it relates
to the T1's on the WA2.  I'm currently running Tung Sol 5998's.
Thanks.

To me, 421A sounds near identical to the 5998. They bias the same in my amp and swing about the same voltage. Nice quiet tube. The GEC is a 6AS7 and sounds similar to most 6AS7. They are each best in breed for their respective types and tend to be quieter, better balanced, and have better soundstage because of it.

  Just a word to the wise. the Siemens E88CC are not rectifiers. Do not use them in the rectifier slot. Big problems will ensue. Enjoy your new Woo!

Just got a WA2, used in great shape. Came with stock Westinghouse 6080 tubes, which seller said were unused as he had replaced them with NOS. Both of the Westinghouse 6080s are completely microphonic and very noisy. I tried a pair of RCA 6AS7G tubes -- again, completely microphonic and one has low-level buzzing. I've checked the driver and rectifier tubes in the amp, and they're fine. So, can anyone recommend a quiet, non-microphonic 6080 (or equivalent)? I'd like to hear what this Woo can do! Thanks.

Congrats!

Last January I was thinking of buying a WA2, but eventually I didn't. However, in anticipation I bought these
http://www.head-fi.org/t/685870/sylvania-7236-nos-tubes-sold
but never used them. If you're interested, just send me a pm.

Cheers

Ouch...if only you offered it a bit sooner I will jump to it, its just I already ordered one pair from Woo directly.
Thanks for the offer anyway.
 
I'm now in the market for a pair of 7308 at the moment

Hi guys...
Anyone ever tried/used WA2 as pre amps before ?
I have Alo PanAm, will the pair work ?
Don't want to experiment it just in case someone had tried it before and destroy them.
 
Really appreciate the input.

I use a WA2 as a pre amp to an Emotiva UPA-2. Sounds just like a WA2.
