300B Tubes

TJ mesh plate 300B

Curve tracing vs single point test. Tube factories matches tubes based on a single-point measurement. But we performs one to two hundreds mesurements in order to plot the curves. Therefore, our test can revealĀ  tube characteristic that is hidden in other tests. Hidden problems can also be revealed.

Why is matching important for tubes? Each tube is different from one another due to the handmade processing. You may be surprised how two tubes perform differently even though they are labelled as “matched” with the single-point test. But power tubes are so critical that matching them carefully can make the music more alive!

The curves also can reveal problems that is hidden. It can reject problematic tubes in the early stage and reduce defective / return rate. It means it can save you possible future shipping cost.
