On a more serious note, though you might not easily see distortion on a 'scope, it'll be there...
At low B+ voltages, these tubes will work but create a lot of even-harmonic distortion which, as it happens, are not too harsh on the ear.
The original design was by a Korean guy called "sijosae" on DiyAudio years back - lots were built in the mid 2000s based on 12AU7s and 6DJ8s - most of the eBay ones are variants of this...
The 6N11 is similar to the 6N1P (actually a Russian 6Н1П) which is in turn similar to the 6DJ8, so all these designs are related.
A typical schematic is shown below:
