EL34 RESERVE
The Ray Tubes EL34 RESERVE Vacuum Tube enhances your amplifier with exceptional improvements in clarity, texture, and detail, thanks to meticulous, engineer-led selection. Designed to unlock your ampʼs hidden potential, these tubes transform its output far beyond the original sound profile, making them a substantial
upgrade from standard NOS tubes. Each tube undergoes meticulous selection and quality checks, featuring gold pins for enhanced conductivity and durability, making it the supreme upgrade for high-fidelity applications.
Ray Tubes is revitalizing the vacuum tube market with hand-selected, rigorously-tested tubes, backed by a 1-year warranty that underscores the quality and reliability of their products.
RESERVE COLLECTION
The Best of the Best
The RESERVE Collection artfully designed and carefully manufactured solely for hifi audiophile devices. Vocals are smooth and lifelike with compelling delivery with superior decay, offering a realistic and immediate presence. The treble is crisp but carefully balanced to avoid harshness. The low-end is full and commanding. The result is a sound that is hard to beat.
Engineered Exclusively for Audiophile Systems
Explicitly engineered for audiophile applications, the RESERVE Collection of vacuum tubes are crafted through a unique process that targets the specific needs of music lovers. Every aspect of their design and manufacture is aimed at enhancing the listening experience in high-fidelity systems, with a focus on critical sound characteristics such as vocal realism, texture, and extended bass.
Magic Coating
Ensuring Excellence
Every vacuum tube in the RESERVE Collection is subjected to a stringent quality assurance process. An audio engineer personally assesses each vacuum tube against a detailed checklist that includes sound profile, dynamics, microphonics, gain, conductance, and noise levels, along with overall performance. This ensures not only that the vacuum tubes align with audiophile expectations for sound quality, but also that they meet our rigorous standards for reliability and consistency.
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.
RAY TUBES QUALITY CONTROL
Step 1 – Extensive Burn-In
Each tube undergoes a 24-hour burn-in period to stabilize components and identify early signs that might lead to premature failures later on.
Step 2 – Comprehensive Parameter Testing
Tubes are tested against more than a dozen critical parameters like amplification factor and internal resistance.
Step 3 – Individual Measurement Recording
Measurements are logged under each set's unique serial number for traceability.
Step 4 – Current Draw Analysis
Industrial-grade instruments measures current draw to ensure fully-accurate matching. This guarantees that each channel outputs similar sound quality and volume, preventing any imbalance.
Step 5 – Microphonics Testing
Tubes are subjected to physical stressors to reveal any buzzing or defects. This ensures that the tube maintains low noise level even in challenging environments.
Step 6 – Functional Testing
Tubes are installed in amplifiers to assess real-world performance. Because there are many nuances of the final sound that cannot be assessed through objective measurements, our sound engineers listen to the tubes on purpose-built equipment to guarantee that they meet our quality benchmarks.
Step 7 – Expert Listening Sessions
Audio specialists randomly select certain tubes that have passed all previous tests and evaluate their sound quality.
