  Thanks very much, that is just what I needed. I see the 12AX7 is not in the list at all. How do the 12AU7's sound with the adapter? 
What is your favorite tube. Do new tubes measure up to NOS?


DO NOT put 12AU7, 12AX7 or any of that family in the AUNE. Even with the adapter it is ill advised. There is a pretty comprehensive list of acceptable tubes, all with their own benefits...stick to those...just a handful to try is going to cost as much as your AUNE..no need to play in other tube families...LOL

12au7 with an adapter sounds great in the Aune.......it is not something I would call ill advised.

Hmm...well, I said Ill advised for two reasons. 1) There is a plethora of tubes to chose from in its class to not go into another tube family with an adapter 2) You have tested that it works...but not prolonged...look at the recent tube meltdown ?
 
No offense is meant, just preaching caution...

Meltdown was poetic license on my part ..his tube didn't melt down...stopped working after 2 weeks

And in every post about that 5 volt tube I said it might not last.

I am being the guinea pig here so no one else makes a mistake. I have been using a 12au7 for well over a month now. If you compare the gain, plate resistance, and so on, they are very similar to the 6dj8. The only pin difference is the center tap heater.

I have enough exp with tubes that if I say it will work, it will.
