Good to know but changing the heater is not for the faint of heart ? Doesn't the 12AU7 require higher on the heater and put out less gain than a 6DJ8?

 

[lwrs10]

  Plus..I have one on the way...
 
But as I have said time and time again...okay.,.maybe once but what I have said is, these will sound different on different systems. They may have similar qualities (such as detailed, forward mids, etc.) but can also diverge depending on the system. Example, I found the amperex globe a bit bass heavy but still agreed it was detailed, forward mids, wide soundstage...etc.
 
So what I am saying is, not everything is guaranteed...I still want to try a 7308..but I just have to cool it for a while..I can get a bit OCD on tubes ..but you guys would not know what that's like.,..right ? LOL

 
 
Know what its like? Nope......not at all.....
 
I keed.

Lwrs10...can you post the process for making this work with 12AU7,,I have some beauties I would love to try...Thanks

tie pin 4 and 5 together on the 12au7, connect to pin 4 on aune.
 
connect pin 9 on 12au7 to pin 5 on aune.

Um..no...LOL
 
An adapter would be nice
 
would something like this work>

Maybe I should make some and sell them?

If the price is affordable

Somewhere around 10 bucks I bet would be ok.

Then you can count me in as one of the buyer <3

I bought some socket savers to make these out of. Damn these things are expensive!
 
I will make 2 versions. 
 
One will be a drop in and use the 6.3V heater circuit in the Aune.
 
 
3rd one will be a 6SN7 adapter that is a direct plug and play. This one will have a small circuit in it to bias the 6SN7 correctly. No external power needed. 
 
 
Sound good?

Be sure to check tube list from time to time, it has all the info you need. I already added this socket mod there  
If lwrs10 will give that "small circuit" type adapter scheme also, it would be nice and I will add it to "suitable tube list".

  Tube types that will work with Aune T1:
 
6DJ8, ECC88, 6922, E88CC, 7308, 6N23P, 6N27P, 6N11, 6N1P, 7DJ8, PCC88, ECC189, 6ES8,

6FW8, ECC85 6AQ8, 6L12, B719, PCC85 & 9AQ8->some may sound distorted due to underpowered 9V heater,
6BQ7A, 6BZ7, 6BS8, 6BK7B->some may not work probably due to "too high" mA current draw,
6SN7, 5692, 12AU7, 5814, 6189W, 12AT7*, 6201*.
 
Pending tube types (need to be tested & confirmed): ECC180, 6BC8, 6BZ8, 8BQ7A 
 
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 (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.
Tubes marked in orange are tube types that have been tested by some users but some of them did not work.
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.
 
6SN7 > 6DJ8 socket adapter:

 
6SN7 -> 6DJ8
Pin 1 -> Pin 2
Pin 2 -> Pin 1
Pin 3 -> Pin 3
Pin 4 -> Pin 7
Pin 5 -> Pin 6
Pin 6 -> Pin 8
Pin 7 -> Pin 4
Pin 8 -> Pin 5
 
Pin 9 is not used.

 
 
12XX7 > 6DJ8 socket adapter:

  Pinout to use a 12xx7 tube.
 
Tie pins 4 and 5 together on the 12xx7, then that goes to pin 4 on 6922 side. 
 
Pin 9 goes to pin 5.

  Well.....here is the summary of the 12xx7 compatibility.
 
12AU7.....works well, sounds good, no distortion. Also tried 5814 and 6189W, which is the military ones. So far my Pilot labelled Mullard sounds very sweet. So does that 6189W....
 
12AT7......Works, but too much gain. You can run it half volume on the computer, then turn the volume up louder on the Aune. Also tried a 6201......same thing.
 
12AX7.....No-go all the way around. Too much gain. 
 
5751.......No-go. Too much gain.

Remember, this is all subjective to the listeners ears.

 
Can't totally agree. Imaging presence, sure subjective, but you also have some parameters that should not be so subjective. High detail = high detail. You also have speaker and headphone values side by side which eliminates some synergy issues. The subjective terms always need some explaining imo. I guess if you find better tubes you just have to extend your scale
 
There's a typo highlighted in red

 

[lwrs10]

As I try more tubes, ratings of other tubes might slide around. So far that 12au7 is the best I have heard to me, so it's rated 10 in my books
