Ray Tubes 12AT7 CORE Vacuum Tube
Introducing 12AT7
The 12AT7 is part of a large family of dual triodes that also includes the common 12AX7 and 12AU7 tubes. Its higher gain and transconductance made it suitable for high frequency applications in devices like TVs and FM radios. In the world of audio, itʼs commonly used as a driver or phase inverter in push-pull audio circuits.
Beyond the Ordinary
Ray Tubes’ CORE Collection of vacuum tubes offers the quintessential upgrade for audiophiles ready to move beyond the limitations of standard factory vacuum tubes. Each vacuum tube is hand-selected, with a strict process that allows only the top percentile of a production batch—those that meet and surpass their rigorous standards for gain, conductance, noise, and microphonics—into your audio system.
Choosing Certainty: Why New Stock is Better
When you buy our CORE Collection of vacuum tubes, you’re guaranteeing that your listening is enhanced by the best of today’s technology. In contrast, when you buy New Old Stock (NOS) vacuum tubes, you’re venturing into unknown territory. While NOS vacuum tubes carry undeniable vintage charm, they often come with hidden risks. Over time, even unused vacuum tubes (hence the “new” in “new old stock”) can degrade, leading to reliability issues and unpredictable performance. You might face diminished sound quality or even failure, as age affects the components, making them more susceptible to wear and damage. In contrast, Ray’s newly manufactured vacuum tubes carry the latest technological advances and stringent quality controls.
Curated by Audio Engineers
The secret behind Ray Tubes’ exceptional sound quality lies in the hands of their dedicated audio engineers. Unlike the impersonal selection process for NOS vacuum tubes, which can be hit or miss in terms of quality, their engineers are deeply involved in every step of choosing their vacuum tubes. They don't just look at specs or conduct standard tests; they listen, evaluate, and hand-select each vacuum tube. This human touch ensures that every vacuum tube Ray produces not only aims to match the vintage experience but significantly surpasses it in reliability and performance.
Silk-Screen Printed Logos
Even the logos deserve a special mention. Silk-screen-printed onto the tubes, they demonstrate Ray Tubes’ commitment to superior craftsmanship down to the smallest detail. This time-honored printing technique yields results that are not only aesthetically pleasing but also durable, ensuring the design work remains vibrant and intact over time.
Superior Sound, Secured
An exceptional 12-month warranty—a rarity in the world of vacuum tubes, especially NOS vacuum tubes—reflects Ray Tubes’ confidence in their vacuum tubes’ performance and durability. This warranty is your safeguard against any manufacturing defects, making sure that your investment is protected.
