This listing is for a spectacular condition 1966 British Brimar ECC81/12AT7 2160 code branded for Raytheon with black plates, large halo getter and copper grid posts...It's almost perfectly balanced, tested way in the NOS range, exhibited extremely low noise/microphonics in the Super Champ where it performed perfectly...The Brimar 12AT7's are highly respected in all their version revisions, and for good reason...They're organic, tight, punchy, pretty consistent British tone across all versions, and this era was on the warmer, more lush side...And this one is surely as strong as it ever gets...

Average NOS test results for ECC81/12AT7's is 4000 microhmos on the Hickok 600A...

Average NOS test results for 12AT7's range from 8-10 on the Orange tester, and the closer those numbers match the closer the tubes match for Gm, gain, plate current/voltage, emissions, etc...

Tube 1...5900/5600 and Match number 12/11

Hello, I am a 12 year tube seller, whose decided to sell my best of the best vintage tubes on Reverb...One thing that may differentiate me from the average seller is that I am a 40+ year guitar player, and close to 30 year high end audio nut that buys, tests, fondles, sells, and altogether spends an unhealthy amount of time with thousands of tubes per year...This makes me an extremely reliable source for vintage tubes...Pretty much all get tested on a meticulously maintained Hickok 600A, B&K 700 Dynajet, and Orange Valve Tester which has been extremely reliable for matching preamp and power tubes..All tubes that go on Reverb will also have been checked for noise and microphonics in either high end tube stereo equipment, or pro audio amplifiers...Not many sellers can say that...

You will receive the exact tube(s) in the photographs, unlike many other sellers who use generic photos and then you receive something else...I will also not claim a tube is true brand NOS unless i'm reasonably certain that is the case, but the vast majority of used tubes I sell here will be in excellent functional condition...If a tube is branded with some other logo, know with 100% certainty that I have identified it correctly, and it was manufactured by exactly whom I said it was manufactured by, and that's truly what you care about...Feel free to challenge me though if you feel up to it😉

Shipping is $6.95 in the U.S., $17.95 to Mexico and Canada, and $24.95 everywhere else...I will combine shipping of 2 or more purchased listings at a rate of $2.00 per listing after the first one...
