Description
This service provides professional computerised testing of 845 and 211 directly-heated triode (DHT) valves on the state-of-the-art AMPLITREX AT1000 lab-grade valve tester — the gold standard of valve test equipment.
The AMPLITREX AT1000 measures plate current (Ip), transconductance (Gm) and checks for gas contamination. Upon completion, you will receive a detailed report of all measurements, making this service ideal for matching valves for amplifier builds, verifying the condition of acquired NOS stock, or diagnosing problems in existing equipment.
Melbourne drop-off available by appointment. Postal testing also accepted — please contact us before sending. Call 04 210 477 48 or 03 9830 8220 for enquiries.
