Running this tube combination right now in my WA6/HD600 rig - wonderful sound. Really takes the WA6/HD600 setup places I didn't think it could go.

 

Not as resolving or technically impressive as my WA5/HE6/HD800 rig, but it sure is fun :smile:

That WA6 Brimar, NU and HD600 rig is fantastic. If there was no top tier options I would be happy with that rig. :wink_face:

 

It is very relaxing.

It's lovely and easy listening for extended periods. The WA5/HD800/HE6 is great, but intense, and can get fatiguing after a while.

 

Really tempted to hook up the WA6 to the Vega DAC and see what happens. Might give the SQ a boost.

Wow, so many great Woos here! I only have one WooWA3+, and I made the tube cage out of 3 square computer fan mesh I found on ebay. It's a bit ugly, but I feel safer than without it.

Very cool dude.

 

I'm a little more uncaring I suppose. I have two boys 10 and 6 years old.

 

I simply said "those tubes get super hot. if ya touch them they will burn badly. Will probably burn ya skin off. So if ya touch them it's your fault. Okay boys?" They have never touched and keep reminding me that the tubes are dangerous. :D I think they got the message. ;)

No worries.

NU 6F8G. Drive tubes

Still rolling power tubes. Kinda funny but I seem to like cheap ones. The Russian 6H13's actually do a lot right and very little wrong. Sylvania 6080 is a wonderfully liquid tube with a lot of bass. Also does not do a lot wrong. I have more expensive power tubes like the TS 7236 and Bendix 6080 graphite plates. They did not impress.

 

Others may find this interesting. In the WA22 you really can't hear much difference between power tubes until you roll into the 6F8G type driver tube. The power tubes all sounded so similar using a 6SN7 driver.

 

Also I was getting a bit of noise from particular power tubes using the eBarf 6F8G to 6SN7 adapters. Once I installed the Glenn adapter all noise problems went away.

I had my RK60 and 6F8G adapters made by Glenn always work fine

Dear all,

Have been lurking for a few months here. None of you know this until now, but I am quite indebted to many of you for all the experience and wisdom you have shared with your Woo gear. It was really this thread that urged me to take the plunge on a WA22, which I took delivery of a few weeks ago. The WA22 is my first ever tube amp, and I've had a blast so far running it on the Woo Audio stock then upgraded tubes fully balanced with my LCD-3fs.

Naturally, the next step is tube rolling, which I will try to do with the benefit of having read (and re-read, many times) some of the related tube rolling threads on Head-fi. To start with, I would really appreciate some help on what must be terribly noob questions:

When I put in a pair of (supposedly) NOS 6AS7Gs yesterday, in the left channel the headphone runs dead quiet, albeit the music that I hear seems relatively "closed" needing to be opened up. In the right channel unfortunately there is strong rustling (somewhat like a radio with bad reception) that makes the music un-listenable - we are not talking just microphonics here. I know it's got to be one of the tubes, because the amp and the whole setup ran without issue on both the Woo stock and upgraded tubes.

As further background which may be relevant: I cleaned the pins with Deoxit lightly though did not leave the solution on overnight; and I also noticed that the tubes went into the sockets with a lot less resistance than what I am used to.

So the noob questions, likely in increasing order of cluelessness, are:

Do tubes, and 6AS7Gs in particular, run noisy and would this go away after hours of burn-in?
Could loose contacts be the culprit / could the pins be too thin? What can be done if anything?
If it's the right channel which has a problem, is it the tube on the right (looking at the front of the amp) that is responsible?

Thanks for all your input, and once again, thank you for having pushed me to the dark side! smily_headphones1.gif

I had a noisy Russian 6as7 type tube the other night i said to myself my tube caught the Badas Syndrome :wink_face: whipped out my trusty sandpaper sanded the pins and it was cured happy camper .Just noticed while listening to my WA6 i am using a SP 274B as rectifier i have distortion in HP could Sophia be on her last leg she has around 600 hours on her i think ill whip out  my sandpaper again and see if she sounds better.  Nope not better how many hours are those suppose to last anyways .Thanks

Hhhmm,

 

6AS7G tubes. The alternative to 6080.

 

6AS7G tubes are not fun. I have discovered this as well. Most are very noisy in the WA22.

In your case it sounds like you have bad tubes. Maybe a loss in vacuum. That would explain it not being good even on music. Sometimes you get background noise but it is not heard in music. I have had what you explained before I just guessed they were bad.

 

What 6AS7G tubes are they? Do you get blue flares in the tube when powered?

 

Now. 6AS7G on the WA22. I have kinda learned by experimenting that 6AS7G does not like the WA22 circuits very much. I had documented here before a history of getting over 50% of them as noisy. That was from a lot of different manufactures.

The RCA type (rebadged Sylvania, Tung-Sol, Raytheon and others) are the worst. Russians are not great either. The only stable one I have found is the early Chatham / Tung-Sols that are differently designed to the RCA. I have not tried the 5998 type.

Here is a interesting discovery tho. As soon as I went to a 6F8G driver all my noisy power tubes went quiet. I don't understand why. I'm just guessing that the 6AS7G power tube reacts badly with a 6SN7 driver. It is a early discovery of mine so I need more time to understand it. However I'm busy rolling power tubes at the moment (10 variants) and they are all quiet. Go figure. :confused:

Glad I have a WA6…great tube rolling choices/very reasonably priced (and the WA6 itself) and sounds awesome!!! :smile:
