Hi, I like to copy this RIAA amplifier for mm

Since I can not source 5755 tube may I use 6N9C instead, which is electrical equivalent of 5755.

I will be most obliged if someone knowledgeable confirms.

Regards

why you dont use "ECC83" its more common and easy to find, recently i made a experience with ecc 81 and its sounds very nice.
