Northern Electric 12AU7 | What a pleasant surprise!
by Ray M. -
I'm 62 and I've owned and rolled a LOT of tubes in my life. Like so, so many it's absolutely ridiculous not to mention expensive. But man, these babies are a certain kind of sweet. I'm astonished at how resolving they’ve become after a couple of weeks of break-in.
Two matched pairs of NE-12AU7 are currently in the signal path of an xDuoo T-20 balanced tube headphone amp fed by a Topping D90 DAC. At the opposite end is a pair of Hifiman Arya planar magnetic headphones. The sound is nothing short of glorious.
I hadn't heard of this tube manufacturer until I happened upon some glowing reviews. In my humble opinion, Northern Electric is a brand that can and does hold its own against the best of Mullard, Golden Lion, Psvane, Electro-Harmonix, and Tung-Sol. Nice job.
Finally, a special shoutout to the Tube Store for matching, carefully packaging and shipping these precious little gems to me. Much appreciated.

Northern Electric 12AU7 | New life for a tube buffer
by CL
I purchased this NE-12AU7 for my Decware Zstage tube buffer when the stock tube reached end of life. I use the Decware between my Denon 110th anniversary SACD player and my McIntosh C47 preamp. After a brief burn-in, the tube sound is greatly improved over the stock tube with greater depth, space, and soundstage. This was an excellent purchase and superb value. Highly recommended upgrade
Northern Electric 12AU7 | A Superior Phase Inverter
by Chris -
I have been tube rolling my Sunvalley SV-EQ1616D and its very interesting indeed. I had not realized that the V3 socket, a phase inverter, had so much affect on the sound.
It seems to rule the stereo stage and affects the tone as well. I got a Bimar 12AU7 with the tube set I bought. I was eventually unsatisfied and dropped in my British Gold Pin Mullard 6201 and it both did a better stage and sounded better. Then I tried my Brimar Yellow Triangle T 6060 12AT7 and it too was very nice.
Got my Northern Electric 12AU7 a day or so ago. Stuffed it in and really the best I have heard in that socket. The sound stage is just superior. Very well laid out and even across the stage. The tone may not quite be up to my grail level tubes, but damn, it is brand new. I look forward to it developing its tonal signature as it burns in a bit.
Looking forward to my matched pair of Northern Electric 12AX7s which are on the way and so far I'm very impressed with the brand.
