Also ECC88 seems to be 365mA actually. Would be interesting to get answer from superlux about how much mA Aune T1 can handle.

 

Just heads up, wouldn`t be sure about those noticeable higher currents because it might work ok but it puts higher drain on Aune T1 and might eventually kill some internal components. But so far I haven`t had any problems with my ECC189 and ECC85 is by numbers only ~70mA higher though, it might be just the "limit" for Aune.

Who knows, just be warned. I won`t add this tube type to my tube list yet because we need more information. 

 

Also about Mullard ECC85 sounding better than Amperex 7308 - it`s totally subjective and may not be the case with everybody.

 

 

I think you missed the point. The original tube offered in the Aune was a Chinese 6N1P, which has a current draw of 600ma on the heater circuit. If you want to compare specs, the ECC85 is actually closer to the Chinese 6N1P than the 6922 is.

Long story short, the ECC85 draws LESS current than the tube these came with at first.....the Chinese 6N1P.  The ECC85 is not going to hurt a thing. 

 

 

And I agree about the sound....everyones ears.....taste.....and needs are different. To me, on my setup, it sounds better. Hows that?

You are wrong. Original stock Chinese tube is 6N11 and it has current draw 340mA and 6.3V plate voltage.

6N11 is direct equivalent to russian 6N23P which also has current ~330mA.

6N1P is russian tube and someone here bought it as cheap substitute to stock tube and it had bad distorted sound!

6N1P is NOT recommended tube for Aune T1.

The person who bought and tried the Russian Rocket 6N1P was me. Wayyyyyy back towards the front of this thread. It was not distorted, the tube was bad.....one sides gain was low. Since then I have swapped quite a few Russian 6N1P's in there and have been using them for months. I like them with heavy guitar stuff.....like metal. So when I want to hear some metal, I have been throwing in the Rusky. 

 

So there is months of using a tube with a draw of 600ma on the heater circuit in my Aune.

Ok, now everything clears out - ECC85 seems to be suitable tube for Aune T1 ;) But don`t accuse me if it will kill someones Aune T1. Just be warned. Going to try one ECC85 myself maybe. Trying to get that Mullard ECC85 since lwrs10 rated it better than 7308.

post #3846 of 8013

Make sure you get the exact same one i have. I can verify it for you before you buy if you want.

 

Make sure it is made in the Blackburn plant, has copper grid rods, round getter, and the plates have 2 round holes on the sides.

E188CC, ECC86, 6GM8, PCC189, 7ES8, Cca, CV2492, CV2493, CV10320, CV5231, CV5354, 

CV5358, M3624, CV4108, CV5331, CV5464, CV5472, CV8065, CV9838, CV10320, CV10403

6FW8, ECC85, 6AQ8, PCC85 & 9AQ8 (some PCC85/9AQ8 may sound distorted due to underpowered 9V heater). 

 

CV tube types cross-reference: http://www.audiotubes.com/cv2000.htm

Chinese tubes cross-reference: http://www.audiotubes.com/chinese.htm

 

Tubes marked in green are tube types that I personally have tried with Aune T1 and are working with no problems.

 

Now, anyone going to try 6DT8? ;D This is crazy - so much tube types to choose & buy! Aune T1 rocks! ;P

 

EDIT: Seems that 6BQ7A / 6BZ7 / 6BS8 (400mA / 6.3V) should also be compatible! Can somebody try and confirm?

Well the 6H30P also looks compatible.....but the 825ma heater draw might be too much. Time to take apart my Aune and see how much it can handle.....

post #3849 of 8013
It probably wouldn't be too difficult to put together a socket adapter with its own heater supply, it could even be selectable for 6.3, 7, 9 or 12.6v. If nothing else it would be fun to play around with.

Curiously waiting for pics and measurement results. Do you have 6BQ7A / 6BZ7 / 6BS8 tubes to try? Keep us updated!

post #3851 of 8013
6BZ7, 6BQ7A, 6BS8 all work.

Another one, too... 6BK7B has a higher heater current draw, some work, some don't. I've tested RCA, Tung Sol, Westinghouse and GE. All but the GE worked. It was not just a bad tube with the GE as I have over 50 of them and tested multiple.

Yeah, I was looking at those...LOL..great ..ebay battle

That`s interesting because 6BK7B requirements are 6.3V and current is 450mA. Wonder why those GE tubes didn`t work, because as we know, ECC85 has 435mA current draw, not much difference.

 

Will add 6BZ7, 6BQ7A and 6BS8 to tube list.

LOL, couldn`t even see it @ eBay and it`s already gone! ;D Please give us impressions VS. Amperex 6GM8 & GE (Valvo) 6GM8. I`m really interested because Amperex 7308 has been quite a "reference high-end tube" until now and now Mullard ECC85 might even be better. I`m skeptic about it actually in terms of "holographic" sound.

post #3855 of 8013

Well Ill be damned......found a Valvo ECC85 in my pile......so far its the winner. But a few hundred more tubes to go!

 

 

Next up is trying 10 or so different 6SN7's I have laying around with an adapter I have.
