When I was surfing the web shopping for some telefunken matched pair 12au7 for bhk pre or quad matched 6922 for the bhk300.
I realised there are options of having it as a balanced triode matched pair or quad matched pair as follows.
TELEFUNKEN ECC82-TK MATCHED PAIR
TELEFUNKEN ECC82-TK W/ BALANCED TRIODE MATCHED PAIR
TELEFUNKEN E88CC-TK QUAD MATCHED
TELEFUNKEN E88CC-TK W/ BALANCED TRIODE QUAD MATCHED
SHOULD I go for normal ones or balanced triode versions for the bhk pre or bhk300s?
Will there be any issues if I chose balanced triodes vacuum tubes and replaced it in the bhk pre ?
