Is 6N1P = 6N7 = ECC31

Hi,

Wondering if the 6N1P is equivalent to the 6N7 and the ECC31.
Looking at a tube linstage with 2 6N1P and wondering what alternative tubes can be tried (other than 6922/E88CC with reduce heater current)

Hi,

Don't forget the ECC31/6N7 is a common cathode type, the 6N1P is not.

Cheers,😉
