Okay is this unjustified?
 
RCA 6080 (1 pair quiet)
Tung-Sol 7236 (1 pair quiet)
Bendix 6080 ( 1 pair quiet)
GE 6080 (stock set quiet)
GE 6AS7GA (7 sets quiet)
Tung-Sol 6AS7G (3 sets quiet)
Thomson 6080 (1 set quiet)
 
Mullard 6080 (3 sets all noisy)
Sylvania 6080 (3 sets all noisy)
GEC 6080 (1 set noisy)
Tung-Sol 6AS7G (1 set noisy)
Russian 6N13 (5 sets noisy)
RCA 6AS7G (5 sets noisy)
 
All noisy tubes tested in WA2 and it is quiet.
 
WA22 is a hit or miss with 6080 power tubes. I'm not the only owner as well. A few of us have tried to fix this. We are talking via PM's of fear of getting banned. Mine has been to a shop to be checked out at my expense. Comment was "work looks fine, it must be the circuit design".
 
Contacted Woo for the second time for comment and so far no response.
 
Either we got a change in the circuit design at one stage then Woo corrected or a batch of WA22's got some bad components. Either way trying to get it fixed or answers is frustrating.

 
I have been out of the loop for a while, is something changed on WA22 design?  I don't recall 6080 is noisy at all, the GEC I had was dead quiet.

It seems that a few people that have a wa22 produced around a year ago are having issues.

  That is unfortunate, why would you mess with a great amp unless it is a major overhaul.  

 
I think they didn't mess up the design. There has been a batch of faulty components supplied.

Joe (is that your name, sorry if is not),
 
Do you still have that set of Mullards?
 
I think I will talk to Woo again and tell them that you have a set of Mullards that have worked properly. Then if I can buy them off you and test in my amp. If it is noisy (very likely out of 6 tubes I have had one is quiet) then it should highlight that there is a issue. Problem is getting Woo to understand that WA22's from a year ago are not working as advertised or like previous or current models. Did you get the Mullards from Langrex? That is where I got all of mine.
 
Is this agreeable?

All good,
 
I checked it out on eBay. There is already a bid. Might as well let that person grab them.
 
What I think I will do is find my noisiest Mullard tubes and send them to you. Would you mind testing?

Great. Thanks.
 
The tubes are in great condition. No shorts. So it won't do any harm to your amp. They are just noisy in mine.
 
Once tested you can keep them or sell. Up to you.

Thanks for the heads up! Im gonna order one now.


I like the look of the little brushes designed to go down the sockets. It is a good starter kit.
 
Get extras of the normal DeOixit tubes as well. They don't go far.
