Hi guys,
I'm interested to order the WA22 but I wonder whether it's possible to tube-roll it to sound dynamic, fast and energetic as the WA6-SE? Have you WA22 owners found specific tube-roll for that purpose?
I'm afraid that the WA22 is more into smooth, mellow and tubey WA2 direction rather than the WA6-SE.
Thanks for your help!

I find that the WA22 can be an utter chameleon with different tube combinations. If I wanted something solid-state sounding, I'd go for EML 5U4G, JAN Raytheon VT-231 and Tung Sol 5998, or Mullard GZ34, Mullard ECC32 and Tung Sol 7236. The beauty of an amp that's this easy to tweak and fine-tune is that you'll never get bored of having just one sound signature.

Welcome fellow WA6SE member. We both received them the same week! I wonder if our serial numbers are close...
 
 

Congrats man!

Excellent model and color selection, Earrat! What was your maiden track played on the amp?

 
I've only listened for about an hour, but Debussy, Ravel, and Miles Davis sound pretty incredible. From my experience, every time I upgrade a piece of equipment, my musical preferences change.

Thank you, sir!

Okay, so the how do you order tube adapters from Woo Audio. They are nowhere to be found on their website anywhere. No links, no information, nothing. I'm looking for the 6SN7 to 68FG adapters - a pair.
 
Edit: Well, I just sent $96 to Woo Audio's PayPal with a note that I wanted these adapters. Hope that is all it takes. Man, that seems pricy for adapters. Ugh.

 
Are you sure they are still making them? I ordered probably the first pair of those just after announced and took at least 4 months to get them mainly because they were busy producing other stuff more profitable.
I thought they decided to stop that because they were not very profitable for them. They are beautiful but mine were noisy because the wire of the grid cap was too thin and not insulated so they were picking up noise from the 300B tubes. I end up sending them to Glenn to get the wire and cap replaced and now they are silent.

No, I am not sure they are making them. I found the Woo Audio thread announcing the adaptors and saw that they never added a post saying they were no longer selling them. However, trying to figure that out with no product, comment, or even FAQ about them is really irritating.
 
I'll have to email Jack and ask him to refund the PayPal unless they are still selling them and ship within a week or so. My 6 week wait for the WA22 was enough for me. It looks like its a chinese or korean adaptor from ebay now since I can't find one anywhere.

Totally. Not too hard to find combos that are faster / leaner than I want (and that's with my LCD-3s).
I have all those tubes except the ECC32s.  I agree a GZ34 would be a good backbone. Then some sort of 7236 power tubes for nice, hard attacks. Bad boys, those Raytheons, or maybe Sylvania 5692s for drivers? Loads of others too.  
 
I've also had some nice synergy with EML 5U4G + GEC 6080 + Sylvania 5692. But that's a very different, tooby sound.

I would be very surprise if they can ship them in less than 4 weeks but is best to contact Jack.
 

 

[Sid-Fi]

Thanks for the heads up. I'll probably send Jack an email tonight.
 
I notice there are only a couple of sellers on Ebay that produce these adaptors. They are sourced from China and Korea if I recall correctly. The pictures of the adapters don't look very impressive at all, but the sellers have fantastic reviews. Does anyone have any experience with these sellers - leemoom611 or ayumitubes?

Some Ebay sellers that produce these adapters uses very thin grid wire that is not attractive at all and could pick up noise more. Some adapters will not fit the Woo very well.

Sid-fi...   When I bought my tubes off of Ebay they came with adapters...   but they are not the adapters that would fit a WA6.. they look OK and I'm sure they work fine... just not sure on what
amp they were built for...
 
I ended up getting a set from Glenn...      anyway...  if you decided to get them from Ebay, Jack Woo or Glenn make sure you ask for the correct adapter or you may end up with an adapter
that you cant use....  just saying, be very specific about what you want when you order them...

Question about the low and high impedance outputs, apologies since I'm oblivious to sound science.  Currently using the WA5 high impedance out with my T1, and I'm finding the gain from the ECC32 sometimes has me leaving the volume knob at under nine'o'clock.  Is it true that if I switch to low impedance it would give me more control over the volume (as in letting me go further on the volume knob without going deaf)?  Also, would that impact the sound quality?  Dunno if it's hearsay but think I saw a post mentioning that on here once as a solution.
 
Thanks all !

It will lower the output impedance a little bit.  Power transfer is ideal with the output impedance of the amp and the impedance of the load are closely matched so by widening the impedance mismatch against your high impedance T1s you are slightly reducing the drive capability of the amp for this load and this is where the slightly reduced volume is coming from.  It shouldn't harm sound quality at all, but it is safe to switch the mode while the amp is operating so you can always flip back and forth and compare for yourself.  If anything it provides better damping which should improve bass control a bit.  That last part is pretty hotly debated btw.
 
A second option is to reduce the input signal going to the amp.  If your DAC is outputting a strong signal to the amp that is part of why the volume range is limited amp side.  Mine is 2.25V for exampe which is pretty average but some DACs put out a lot more.  Most CD players are 2.0V or less.

Good news. Jack replied quickly and said the 6NS7 to 6F8G adapter I ordered would ship within a few days. Glad to know Woo is still making them and getting them out in a timely manner.
 
I also jumped the gun and ordered one of the cheaper ebay adapters since I wasn't sure if Woo was even making them. At least now I'll be able to compare the Woo adapter to the ebay one and let others know how they compare. The pair from ebay was $30 compared to the $90 for the Woo, but the latter certainly look nicer. Here is a pick of the ebay one I ordered from seller zhangsheng. The wire definitely looks thin and I could picture it picking up noise, but who knows.
 
I'll post a picture of the Woo adaptor below. Looks nice but also very thin wire.

That's good news for you. Let us know if the Woo pick up nose as mine did.

This certainly speaks to Glenn's work being one of quality.
