  Agreed.
 
My third Ecc85 arrived today and it's distorting very badly.
 
So the Siemens (ebay # 121349434162) was a none starter in the Aune.

Tubes marked in green are tube types that I personally (and some other users) have tried with Aune T1 and seem to work with no problems.
Tubes marked in blue are tube types that other users have tried with Aune T1 and seem to work with no problems (not tested by me).
Tubes marked in orange are tube types that have been tested by some users but some of them did not work, probably due to "too high" mA current
draw or may sound distorted due to underpowered 9V heater.
Tubes marked in red are tube types that require custom socket adapter to work. * means that it has too high gain and
volume output level should be reduced from PC control panel.
Tubes marked in pink are tube types that do not require socket adapter but these tubes use higher current draw and might not be safe to Aune T1 internal components but according to user lwrs10 can be used safely. I`m not responsible for damage that may occur. Use with your own responsibility!







 
 
If You read carefully and look at colors, then I personally have NOT approved to use those tubes and I still don`t.
Why? Because I have bought 7 different ECC85 tubes that are TESTED GOOD and ALL of them are with distorting sound.
And two out of those are "high grade" Telefunken & Siemens ECC85. Also one Ultron and one RFT.
Others I don`t remember atm. I know few users hyped the sound but it is quite hard to find those ECC85 tubes
with exact same physical construction and manufacturer. I tried to get one with same construction and
manufacturer under different labeling but no luck - distorted sound. I decided to give up finding working one and
I do not approve hyping about that tube type. It doesn`t mean that there aren`t no great sounding ECC85`s out there but
it`s lot of gamble and seems that risk getting distorted sounding tube is quite large. About PCC85 - I have two that work great, one
is good sounding and second is amazing - Siemens E88CC goldpin like. But I still do not recommend those to others because I
also have 4 of PCC85 that are also distorted sounding like those ECC85`mentioned earlier.

Feel free to post this information to the thread.
Well, actually I recommend to do it to avoid users ending up with distorted tubes or at least warn them
about high risk of it :wink:

Cheers!

I just got a message from CoiL saying that he has run into the same issue where some ECC85 distort and some don't, it's a bit of a gamble.
Wish I knew that before I got another ECC85 tube, as now I have 2 tubes that are practically useless to me. Oh well :p
Now I have to find another tube that is confirmed to work, does anyone know of any other tubes that are similar in sound to the ECC85?
 
Edit: Weird, thread didn't update with new posts for me until after I posted.

How does the tube code above the date code relate to tube model? The Siemens ECC85 you purchased was a "tU6", my GE ECC85 is a "tU7".

So I got a little impatient and ordered a couple of tubes, a GE and a Sylvania both ECC88/6DJ8.
Really wish there was something I could do to get my ECC85 tubes working, the GE ECC85 I have sounded amazing during the time that it was working properly.

My Mullard ECC85 is a tU4.

In a past post, Isendono mentioned turning down the mixer volume in windows if you have a noisy ecc85. I think that probably works maybe because the gain on the ecc85 is high enough that the noise floor is elevated as well. Have you tried to see if the RCA outs are clean? You can try running your HPs out directly from there with a RCA to female 3.5mm jack. Make sure to turn down the volume in window's mixer because you do it tho. Worth a shot I guess. :)

Put in my GE ECC85, line out RCA to 3.5mm in on my FiiO E17, still getting distortion.

I got the camera out and zoomed in and it seems my Mullard ecc85 is 1u7 delta 4H1 (not 9H1 as advertised) (delta meaning a triangle on it's side)
 
The 1u7 part the 1 is just a small stroke so I'm guessing a number 1.
 
I sorry if anyone has bought an ECC85 because I said that my two were better sounding than any ecc88 and then found their new Ecc85 distorted when played.
 
I too have now bought a third  and it distorts badly.
 
However, unless someone tells me the ECC85 is going to hurt the Aune T1, then it will be in there a long long time.
 
It's superb (or for most of the forum "Awesome", the first and only time I will use the word.) Showing my age I guess

Bummer. :frowning2: That at least removes the amp as a culprit. I think a disclaimer should be placed on the ECC85 as a tube. It's too hit/miss to safely recommend unless you can get it really cheap.

I was really hoping this was the source of my problems. Turns out that it still turns out static--y. Although, this may also be from the amp idling for a long while before I actually plug in my cans. I'll update and let you guys know.

Bummer again.
