SELECT COLLECTION
Even Better Sound
The SELECT Collection not only maintains the exceptional manufacturing quality of the CORE Collection, but delivers a significant leap in sound quality. Engineered for audiophiles who want an immersive auditory experience, this tier far surpasses what standard factory vacuum tubes can offer.
Make Your Good Amp Great
The SELECT Collection significantly upgrades the performance of your vacuum tube amplifier. These tubes are engineered to bring out better sound from your amp, transforming its output into something far beyond its stock configuration. Each tube is handpicked by our engineers for enhanced clarity, texture, and detail. Every note resonates with more realism, every harmony carries more emotionality, and every rhythm pulses with tighter low-end precision.
The SELECT Difference
While SELECT vacuum tubes come from the same batches as our CORE Collection, they stand out for one reason: expert judgment. Our engineers assess each vacuum tube individually for its sound profile, dynamics, microphonics, gain, conductance, noise, and overall performance. This human touch ensures that only tubes that meet a superior level of sonic excellence make it into the SELECT Collection.
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.
