Welcome to the Outpost!
We work hard to ensure that all tubes/valves are fully tested under real world conditions with the most advanced test unit available, the Roetest tester designed by Helmut Weigl. Each valve/tube is provided with the full test results that include vacuum test, filament test, testing for shorts, transconductance, percentage of nominal plate current, leakage, and includes full curve traces.
Other parts and components are fully tested with advanced ESR, LCR and Transistor testing devices.
Unsure what you need? We'll be publishing explainer videos on YouTube soon, but don't hesitate to reach out with questions, we love to help others learn as we remember when we learning ourselves.
