Oh my... you just opened up another "level" of Aune T1 ! Now we need schematic for building that adapter!!!

its very simple. Pin list is from the 6SN7...
 
 
6SN7..6DJ8
Pin 1 to 2
Pin 2 to 1
Pin 3 to 3
Pin 4 to 7
Pin 5 to 6
Pin 6 to 8
Pin 7 to 4
Pin 8 to 5
 
Pin 9 is not used.

Thanks! Can`t wait to try this ;P Let us know when you find some good sounding 6SN7!
 
Edit: Just for information 6SN7 is 6.3V / 600mA

Well, this RCA Ruby Base makes a clean electric guitar come out and dance on my desk. Still some treble issues.....but bass is great overall. 
 
 
My next adventure is 12AT7, 12AU7, and maybe a 12AY7. Can't do a 12AX7 since the gain is too high. Only have to swap 2 wires to make the whole 12XX7 series work.

Can you tell for what pin9 "internal shield" in case of 6DJ8 etc. is needed for? Isn`t it dangerous to "remove" that pin9 in case of 6SN7 > 6DJ8 adapter?

Please be kind and give us pin-out "schematics" too for all of those types. I will later make proper schematics to everyone to try! There are many who would like to roll their 12XX7 series tubes!

  Well one of those Harmon Kardon ECC85's is bad.....damn. 
 
 
 
Lets see what type of reaction this gets......
 

I noticed your Aune is hooked up to another amp ,wouldn't this be little off for comparison since most will only use standalone T1 ?
 
as for Harmon Kardon ECC85...there is a bunch on ebay

That`s why I don`t stop repeating that there are many nuances that make tubes sound different to ppl.
But atm I`m mostly interested just trying other "new" tube types with adapter rather than chasing tubes with little analytical comparing and only 1 user opinion (don`t take it bad way lwrs10). Your effort is highly appreciated by me & surely by others!

Did you tested those types by yourself or was it just assumption by tube requirements? Asking because then I know if I will add them to "blue" tube list

Yes, everything I've said will work comes after testing them myself.

Well heck..I have been asking about this..I have a BUNCH of 12AU7's (and 12AX7's) but you say 2 wires need to be swapped? I though there was already an adapter somewhere on the bay ?

  It does not control line out, only headphone jack out.
 

 
Ok, thanks for that.
 
Let me know how crazy this sounds to you guys:
 
My current setup is:
 
Dedicated computer loaded with FLAC and SHN music.
M-audio Audiophile 2496 soundcard > Adcom GPT-350 preamp > DBX 234s crossover 
      out of the crossover:   Low - Polk Audio pwr subwoofers (L and R)
                                       Mid - Crest FA901 
                                       High- Ashly 1000M 
 
I want to remove my Adcom solid state preamp as all of my music now comes from dedicated computer/hard drive.  It was good for 20 years but time to move up.
 
I'd like to come out of the PC via usb to the Aune T1 and go straight into the DBX crossover but I can't control the volume from the Aune T1.
 
How would you guys feel if I were to put a USB volume controller into the PC and have it control global audio settings out to the Aune ?
 
something like the griffin powermate:  http://store.griffintechnology.com/powermate
 
 
now I could control audio out to the Aune.  I could also assign other functions to the powermate (press to mute....etc)
 
What do you think?  Other suggestions?

The fact that I am using speakers instead of headphones should not really matter. I am very familiar with how it sounds, so I can hear any change. Speakers will sometimes show more than headphones, and headphones will sometimes show more than speakers. I can very easily plug in some headphones I have and compare also, which I will do after all this initial impression stuff. 
 
 
 
I am trying out an RCA JAN 5692 right now, which a military version of a 6SN7, and it sounds very nice. 
 
Building the 12XX7 adapter right now to try out.

Thank you for doing this ,your socket mod looks wild

First 12AT7 did not do so well. But the tube test bad, so time to swap in another one or 30....
 
 
 
And there we go.....swapped in a known good 12AT7. Now we have both channels!
