The GE 6SN7 is fabulous as it had helically wound filaments and is very low in hum. Great tube. And they test well.
Northern Electric tubes, huh? That name is owned by the Tubestore. Check the trademark office.

If somebody wants to tell me how they are any different than another Chinese tube, I'm all ears.
PS I like some Chinese tubes.
