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...
