Have you ever wondered how Ruby Tubes ensures the quality and consistency of their tubes? Let's dive into the meticulous matching and testing process that each tube goes through before it reaches your hands.
What is the Matching & Testing Process?
At Ruby Tubes, every tube is tested within one milliamp to ensure it meets the highest standards of performance. This precise testing process guarantees that each tube functions optimally and reliably in your equipment. Additionally, all tubes undergo a thorough burning-in process to stabilize their performance over time.
How are Tubes Matched?
Matching tubes is a crucial step in the process to ensure balanced performance in your equipment. Ruby Tubes meticulously matches tubes based on key specifications such as gain, transconductance, and noise levels. This attention to detail results in pairs or sets of tubes that work harmoniously together, providing you with the best possible audio experience.
Why Choose Ruby Tubes?
One of the best parts of the Ruby Tubes Matching & Testing Process is that it is completely free for our customers. This commitment to quality and customer satisfaction sets Ruby Tubes apart in the industry. When you choose Ruby Tubes, you can trust that you are receiving premium tubes that have been rigorously tested and matched to deliver exceptional performance.
Plate Current & Transconductance
Plate current is the flow of electrons from cathode to anode within a vacuum tube. Transconductance describes the relationship between voltage on the control grid and the plate current. We test our tubes by applying a standard operating voltage, allowing us to match tubes with similar values and characteristics for the best functionality within your amplifier.
Biasing
Biasing involves setting a specific DC voltage and current to establish stable operating conditions for your tubes, allowing them to function within their specifications. Replacing tubes with a matched set with similar characteristics will result in less variation, allowing minimal bias adjustment. Let us know what Plate Current is on your Ruby Matched Tubes when ordering replacements and we can get you a suitable replacement. Bias adjustment should be done by a qualified technician.
