I  have the 6, 22, and had the 2. I also have two versions of the 4.

 

The WA4 (2004) uses the 6C19, 12AU7, and 6DJ8 tubes.

The WA4 (2011) uses the 6C19, 12AU7, and EZ80 (rectifier).

 

I've never heard the 6se. I would say that the WA4 (2004), to my ear, is closer to the WA22. The WA22 may have an edge because of the rectifier (5U4). But my WA4 has been modded and has Black Gate caps and V-Caps so it has a strong bottom as well. Here are pictures of the WA4 that I purchased. http://www.head-fi.org/t/517160/sold-woo-audio-wa4-upgraded-amp

 

The WA4 (2011) has a cleaner sound (it uses the EZ81 or EZ82 rectifier) placing it closer to the WA2 but with a slightly warmer presence.

it is not possible to buy the 4 anymore. Jack says that there are not enough parts to make the build. So its a no go unless you buy it second hand

yes I know that but am interested how it stands up to my other Woos as looking at the 6C19 valve may make an interesting DIY project.

 

Thanks Clayton, very interesting comments, seems like it is a quality piece then:) The chance of finding second hand for 240v are slim but has me thinking.....may buy some of these triodes to try.

All of my Woo Audio amps have a voltage selector for AC 110v/220v. Would a WA4 220v amp be okay powered at 240v?

post #29016 of 30567

Actually 252v......:( and legit.

Just received emails from woo audio and music direct. The amp and headphone will both be delivered on Friday. I am very excited. On the way of searching for the tubes for wa6se, i saw the Phillips 274b NOS at Upscale Audio with a very good price. Does anyone know how good is this tube compare to the Sophia Princess? Also, any sound differences between the Sophia mesh plate to the Sophia Solid plate?
Thanks in advance.

Thank you, i will pick up those two to put on my wa6se to compare. Just to be sure, are they all compatible with my wa6se, i am so confused since there are so many of the tube rectifiers.

For driver on the WA22, I personally prefer Kenrad VT231 black glass over RCA grey glass.

Thanks for the link. Its a big help. I am very clear now.

Hi, I recently purchased the 6GL7/6EM7 driver tubes for my WA6 to go with the S/P, and I didn't really care for the overwhelming overall bass presence in general. I returned them and am now listening to the 6EW7 driver tubes I received stock with the amp and I do like them, but I would like to try something with a little warmer midrange for vocals, and a more impactful, tighter bass with a bit more extended highs. If anyone has had/have experience with the sound signature I'm describing, can you please give me some suggestions if they can be found on the link below, thank you.

Anybody?

Joseph,

 

 

The option to use 6SN7 tubes with the WA6 by using the adapters are perfect. Their are many 6SN7 tubes that will accomplish your objective. The Sylvania 6sn7WGT would be an excellent choice or another less expensive option would be the WQestinghouse 6SN7 tubes and can be sourced form ebay.
