How do we test our TJ Fullmusic tubes?

We curve trace test each TJ Fullmusic tube by our Amplitrex AT1000 tube tester. Results are exported to a spreadsheet for comparison and matching. Below is a interactive sheet to show the curve and test result of each tube. You can check the test reports before you place your order. The graph will take a […]
