Retro Sound + Modern Build

At Ray Tubes, our love for the warm, retro sound of vacuum tubes inspired us to tackle the challenges of the modern vacuum tube market. Disillusioned by its inconsistencies and scarcities, we set out to blend the best of vintage audio with the reliability of new production. Our vacuum tubes are the fruit of this labor, offering audiophiles the beloved retro sound of the past, crafted with today’s standards of excellence.

The New Standard: Hand-Selected and Rigorously Tested

Most enthusiasts looking to capture the magic of vintage sound turn to auction sites or second-hand shops. These shops often specialize in selling New Old Stock (NOS) vacuum tubes, which, while revered for their authentic sound, are becoming increasingly scarce and exorbitantly-priced. Plus, due to their age, these tubes can suffer from inconsistent quality and performance issues. Unlike NOS vacuum tubes, our vacuum tubes are newly-manufactured, hand-selected by professional sound engineers, and rigorously tested. Our process ensures that every vacuum tube not only revives the experience of vintage vacuum tubes but makes it more accessible and consistent than ever before.


Unlike the market of NOS vacuum tubes, where warranties are virtually unheard of and quality guarantees are rare, we proudly offer a one-year warranty against any manufacturing defects.

Meticulous Matching for Unmatched Sound

An immersive audio experience begins with unparalleled accuracy in the components we use. Each pair of our vacuum tubes is hand-picked by a sound engineer based on rigorous criteria for optimal gain, conductance, noise, and microphonics performance, ensuring that only the best of the best make it through our selection process. 

A brilliant, brilliant new production tube. I don't have anything negative to say. I can't find any cons or negative with the Ray tubes.

Passion for Sound

These proved to be so good, so resolving, yet never harsh, never annoying...instead they combine really smooth and natural sounds with higher-resolving, really open, really spacious sounds that we expect from great tubes.

In one word: coherent...compared to stock tubes they're more clear. They have a more well-defined and solid bass response. The real differences lie in the upper mid-range and treble response. The fidelity of the upper mid-range is actually quite significantly better than that of the stock tubes....the sound-staging width is a lot more substantial.

Joshua Valour can hear more music and less noise...tight...smooth....warm.... I do believe these are worth it if you want to improve the sound of your amplifier.
