Ruby offers a 6-month warranty on all of our tubes! We stand behind the quality and reliability of every tube we sell. If you experience any issues within six months of purchase—such as noise, failure, or performance inconsistencies—our team will make it right.

Simply reach out to us by email or phone, and one of our Ruby experts will guide you through the quick and easy warranty process. Depending on the situation, we’ll arrange for a replacement or issue a credit toward your next purchase.

Our goal is simple: to make sure you’re completely satisfied and confident in the performance of your Ruby tubes, every time you play.

From the second the tubes hit our warehouse, they undergo a meticulous testing and matching process. Each tube is carefully measured for key parameters like gain, transconductance, and plate current to ensure consistency and performance. Our team of Ruby experts—specialists with decades of experience in tube evaluation and matching—personally oversee every step to guarantee accuracy and reliability. We then hand-match sets within tight tolerances so that every set delivers balanced tone, reliability, and optimal performance right out of the box.

Nope! Ruby tests and matches every single tube at no additional cost. From the moment they arrive, each tube goes through our full inspection, testing, and matching process—handled by our experienced Ruby experts—to ensure top performance and consistency. You get fully tested, ready-to-play tubes right out of the box, without paying a penny extra.
