Description
This service provides professional valve testing, matching and grading on the Amplitrex AT1000 — a state-of-the-art computerised valve tester regarded as the gold standard for laboratory-grade valve measurement. The AT1000 measures transconductance (Gm), plate current (Ip), grid current and leakage to an accuracy and consistency far beyond what conventional testers can achieve.
Customers receive a detailed test report for each valve, documenting the key electrical parameters that determine a valve’s quality and usability. This service is ideal for customers wishing to verify NOS purchases, sort and match valves from their own collection, or obtain objective data before committing expensive valves to a circuit.
The listed price covers testing of the first two valves in a submission. Each additional valve is charged at $15. Please contact us to arrange an appointment or to discuss postal submissions.
