CORE COLLECTION
Beyond the Ordinary
The accessible CORE Collection is for audiophiles wanting more than standard tubes. Each tube is hand picked. They meet our high standards for gain, conductance, noise, and microphonics.
New Stock
Our CORE Collection gives you the best of today’s technology. NOS (New Old Stock) tubes have vintage charm but come with risks. Even unused, they can degrade. This leads to reliability issues and unpredictable performance. You might get bad sound quality or failure. Our new tubes have the latest tech and quality controls for better performance and reliability.
Tested by Audio Engineers
Our sound quality comes from our dedicated audio engineers, involved in every step. They don't just check specs — they listen and hand-select each tube. Our tubes match and surpass the vintage experience in reliability and performance.
Gold Pins
Gold pins not only add a touch of elegance but also serve a significant purpose. Gold's superior conductivity enhances signal transmission for crystal-clear sound, while its resistance to oxidation ensures long-term performance and durability.
Silkscreened 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-honoured printing technique is not only aesthetically pleasing but also durable, ensuring the design work remains vibrant and intact over time.
12-Month Warranty
We trust our product. Ray Tubes offers a 12-month warranty — a rarity in the world of vacuum tubes. This warranty covers any manufacturing defects.
