Mazda 6N7G and Svetlana 6h13c
 
Mazda and Visseaux 6N7g are the same as far as sound is concern. I have both pairs and have verified it. Visseaux 6N7g is now with @connieflyer. Next to the Fivre 6N7g brown base, the Mazda 6N7g is the best performer of the 6N7g. It's a brighter tone than both the Mullard ECC31 and Fivre 6N7g brown base. Clarity and details in abundance and on the bright side of neutral, whilst retaining enough warm and lushness. I love the tone. 
 
Unfortunately there are quite a few who have less than favorable experience with them as fas as hum is concern. In my Elise, they are dead quiet and has the most lovely glow of all my tubes.
 
You can pair it with 5998, Bendix 6080wb or even GEC 6AS7G for an even greater stellar sound.

Ok I google translate that. Basically he is saying that Elise is very good and to his surprise even sounded good on his low impedance TH600. 
 
He also mentioned us - i.e the Head-Fi thread for reference.

That is a Tung Sol 6F8G and I believe the adapter is from Feliks Audio because it's shown on their 2A3 amp picture on their website. 

I've used 6F8G tubes with MrsX's adapter as a driver quite a few times in Elise and there's never any hums.

Been using the headphones the whole day so it's time for some stereo music in the lounge. Lets' crank up the subwoofer.

You lucky boi but don't you agree the other adapter is nicer?

  I'm really curious if FA actually makes that.

Yes I agree it does look very stylish in that picture. 
 
I've also been lucky with my present superb sounding set-up as it hasn't buzzed for nearly 12 hours, except when the wife walked in to water the flowers.
 
I think this is probably Elise at her best, for my ears, as long as it doesn't buzz.
 
Note the extra foil on the far right power tube anode connector-that  makes a big improvement.

When the wife looks for the foil and there's no more, you're gonna be in real trouble !!!

Is that a EL11 in brown base?

HAHA I've already been in trouble about using up all the kitchen foil so I went and bought my own supply and have hidden it in my man tube cave.
 
Sorry I should have said those are Telefunken EL11 drivers, and for powers the brown base RNW EL12spez coupled with a Telefunken EL12spez for the left channel, and on the right channel another Telefunken EL12spez coupled with an RFT EL12spez.
 
I would have preferred all the same manufacturer of tube but I don't have enough of them.
 
I think, in the absence of being able to make a well shielded adapter, like H1 has successfully achieved, the solution to the hum is going to be a trial and error individual matter, based on one's own room and local interference, like RF, etc.
 
Interestingly the dual power set-up doesn't hum any more than the single one. I've realised it's better to wrap the foil round the wire a few times, too thin isn't as good, even though it's neater.
 
I've still got my Faraday cage, aka Ikea utensil holder, in case of emergencies, but I've got my fingers crossed just now that most of the humming will have ceased.

Simple solution. Tell the wife not to walk around but she might come at you with the rolling pin. 
 
Orientation is important. You must face the sun.

You can tell I'm sceptical. I was about to post an impression of EL12N as drivers and EL12 as powers because it was so interference free but just as I was about to make the post, it started producing a groaning sound on my right headphone channel with no music playing. I thought I must have heard wrongly so I waited and listen again. Sure enough it came on again and thereafter at short regular intervals. This is getting spooky so I shut it down and have gone back to Figaro. I'll switch Elise to some other tubes later. I'm not sure what's going on. Is one of EL12 tubes going off? When I turn it upside down, I can hear some pieces of glass sound. However I am done buying more EL tubes.
 
Not even if I'm El Desperado !!!

The vibrations from your cranked up sub-woofer has probably damaged that tube. (only joking)
