Really Nice


To echo previous comments on this tube, what a beautiful looking and sounding tube. I added a matched pair of these to replace NOS Sylvania GT green labels in the front position (line stage?) of my Cary SLP-98P (stock EH in the rear position - buffer?). I liked the Sylvanias but these tubes are head and shoulders above. They're really nice from top to bottom and front to back. Mids are gorgeous and the bottom end detail and timber has been improved. Hi end is smooth and open. Overall the soundstage has improved in width and somewhat in depth but the air and dimension has definitely increased all around. They're on the expensive side but IMHO well worth the money. The risk was worth it... These tubes absolutely paid off.

Simply amazing tube


I have schiit freya preamp ant the stock tubes it came with quickly deteriorated in quality so it was time for an upgrade. I did a lot of research as well as borrowed some tubes from my friend to audition at home. They were Electro-Harmonix. To be honest with you they sounded about as bad as the freya’s stock tubes with the exception they had a lower noise floor. I wasn’t happy and on went for more research.

I came across NE but they were out of my price range. Waited for cyber Monday and ordered 4 matched.

First off, I received them in 1 day. Totally unexpected! Amazing service from tube store.

These tubes are bigger and bulkier than the previous ones I had and you can tell they are well made by just holding them.

Once I installed them in freya I left it on for about 20 min to adapt to room temperature and properly warm up and then started playing.

Immediately I noticed that all the harshness I used to hear with my previous tubes is gone!

Also noticed that these tubes have very low noise floor. I literally stuck my ear into my tweeter and couldn’t hear much hiss, hum or cracking.

Sound wise these tubes are simply amazing. Very, very smooth, without any harshness. Good bass but the area they excel are in the midrange and the vocals. Previous tubes they were very sibilant. These tubes are so smooth, it is simply amazing.

In terms of air, placement, space etc. I can’t talk since I am new at this and don’t much understand those things.


Fragile Center Pin


I ordered a matched Quad of Northern Electric 6SN7 for my Schiit Freya preamp. They went in nicely and they sound wonderful - However - Upon extraction the ceramic and alignment center pin int he plug unexpectedly broke off inside the socket in the Freya. I have been working with tubes for over 46 years and this is a first for me. I now have a octal tube that I cannot trust an intern to work with. It could be dangerous to plug in and easily plug in incorrectly.

I'm very much impressed about this sound quality.


Its really good for cary SLP05. I've use this Tube last one year. I had got it from my Canada house through thetubestore.

6NS7 tube rolling revealed that North Electric's are the best.

For my integrated tube amplifier, I've tried several 6SN7, even some of the costlier ones, and the Northern Electric are the best of the lot: dynamics and rhythm.
