  5 Dear Mario
There is no 6n7GT but this is written 6n7s and is the equivalent of the 6N7GT.
Please keep in mind that we write Russian tubes in small letters and transform the letters from cyrillic to latin.

  6 You´re right Ernst, watching 6n7S Jacob Roschy´s photo I can see that is the same tube.
