My expectations were exceeded !

These tubes really astound and provide beautiful midrange and texture. I appreciate the quality and reputation of this Canadian based company. Finally, I was overwhelmed by the packaging and everything reflected an impressive contribution to audio!

Great sound, short lived.


Good sound but short lived or poor QA.

Used on a Elekit TU8600s as pre-amp.

The sound is natural, clear, and musical.

As a matched pair, the right channel one faded to merely audible after 8 months of use, about 1200 hours, far under 12AU7 expected life of 5000-10000 hours (google 12AU7 life expectancy). Switching to another brand of similar price. Will bump the star back if same thing happened again - that could be my circuity problem. Will knock one more star if 12AX7 faded as well.

The other 12AU7, 12AX7 (also NE), and 300Bs (Genalex) all perform strong.

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 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.

tubes come from China, Canada is printed on the box only


Tubes are good, but should be included information about country of production China (Not Canada).
