At Tonal Tubes we match tubes using a tester that enables us to match tubes at high plate voltages as well as various bias voltages. This means that when you install these tubes, they will be a tight match inside your amplifier.
We have very strict standards when it comes to matching. We match power tubes within 5% for plate current and 10% for transconductance. Most other retailers will match to just one of these values, however it is important to have both of these values matched. This is not a simple process and does take lots of time and dedication since tubes can vary so much from the factory.
Having matched power tubes is important because it reduces hum from your amplifier. It also allows you to get more life out of your tubes, since each tube will be working approximately the same amount.
Why You Should Do Business With Us
- Every single tube is checked for shorts and leakage on a calibrated Eico 667 tube tester
