OllyJust one very important note.
This is old type code between the pins used before 1956 for European tubes.
Tube you have was not 12au7 it was 12ax7 for sure.
DX mCP code - Valvo, Hamburg made, June 1955, ecc83, long plate foil getter.
Very nice Valvo ecc83 tube in my top five favorite. Also very rare and old. Oldest Valvo ecc83 is 1954 copper grid long plate foil getter.
k6..(k61, k62, k6P...) in the second row mean ECC82.Regard
