Northern Electric had a rich history of producing high quality audio products and vacuum tubes in Canada. We are now re-introducing this classic brand and bringing to you the highest quality tubes possible.

The Northern Electric 12AX7 is made with the highest quality materials. Everything is designed to give you unsurpassed audio quality. This tube has very large smooth plates. This design is much like a Telefunken 12AX7 / ECC83 smooth plate but a bit shorter. This design provides plenty of gain while maintaining an extremely low noise floor. It has been torture tested in a JTM 45, a Deluxe Reverb, anOrange 50 watt combo, and Bandmaster Reverb, with no failures or noise problems after hundreds of hours in clubs and studios. It doesn’t matter if you use an American or British design, this tube works.

In our listening tests it was easy to hear that the tube did not change the voice of the amplifier as some preamp tubes do. The Northern Electric enhances the sound across the entire spectrum. Our testers have reported no noticeable spikes or weakness in the lows, mids, or high end. The highs are very smooth with a balanced midrange response and warm, full bottom end.

They sound great, really great. But, if you play out and need to depend on them to work, for get it. I bout two and put into a vox night train. They didn't even make it a year with very little play time and no travel within that year (wtf). Too expensive for what you get. I bought NOS RCA's (butt ugly) for $50 per. They look like crap, but sound great. Best of all, they are going on 4 yrs with a hell of a lot more use per year. Give me vintage for the same $$$ every time.

Great sounding. DID NOT LAST!


Bought a matched quartet about a year or so ago. Used them in an audio tube pre amp for hifi applications. I hate to give them a bad review because indeed they were the best sounding 12ax7 I've ever used but at 200 bucks a matched quartet and to not get more than a little over a year out of them and they started to test poorly is no good. No good. What a shame. Sound wise they are nice and quiet and a ton of detail. Went back to using my old telefunkens.

These are great tubes, very clean sounding, low noise and extremely well balanced. The tubestore guys are first rate. I needed some customer service help afterwards, and they replied promptly and totally to my satisfaction.

Sound Great, but Unreliable


I've had two of these fail back to back in very short order in guitar amps. Which is too bad, because they sound great when they work.
