Meet the Apos Ray Vacuum Tube

The New Standard in Sonic Excellence

We at Apos are thrilled to announce the launch of our latest innovation: the Apos Ray Vacuum Tubes. These unique vacuum tubes, painstakingly designed and crafted to deliver an unparalleled audio experience, have been created for those who share our passion for the rich, immersive sounds that only vacuum tubes can produce.

Hand-Selected, Rigorously Tested: Raising the Bar

Unlike standard New Old Stock (NOS) tubes, each Apos Ray Vacuum Tube is brand new, hand-selected, and rigorously tested for optimal performance. This rigorous selection process ensures that only around 4% of tubes, those meeting our strict quality standards for gain, conductance, noise, and microphonics performance, make the cut.

Experience Sonic Brilliance

The Apos Ray Vacuum Tubes promise to make your favorite tracks come alive. Expect sparkling highs, punchy and tight bass, and vocals full of texture and realism. These tubes promise clarity and resolution that's nothing short of a delight to your ears.

Compatible Amps

Our matched pair of 12AU7 tubes are compatible with amps from major brands: xDuoo, Woo Audio, Manley, Bottlehead Crack, Bravo, Little Dot, Original, Cayin, and Cocktail Audio. 

Gold Pins: Not Just for Aesthetics

The gold pins on the Apos Ray’s tubes not only look elegant, but they also enhance signal transmission thanks to gold's superior conductivity. Additionally, their resistance to oxidation ensures longevity, meaning these vacuum tubes don't just sound good—they're built to last.

Silk-Screen Printed Logos: A Nod to Superior Craftsmanship

Our commitment to exceptional craftsmanship even extends to our logos, which are silk-screen printed onto the tubes. This time-honored printing technique results in designs that are aesthetically pleasing and durable, standing the test of time.

Rest Assured with Our Apos Warranty

Each Apos Ray Tube purchase comes with a three-month Apos Warranty against manufacturing defects, so you can buy with peace of mind.
