Valve Performance

At the heart of the Orange Valve Tester MKII is a sophisticated microprocessor that executes a series of complex tests to assess valve performance. The device’s intuitive design requires no prior knowledge of valve theory, allowing users to quickly test valves by inserting them into the unit, selecting the valve type, and pressing ‘OK’. The tester then swiftly reveals the valve’s status, making it an indispensable tool for ensuring optimal amplifier performance.

Enhanced Algorithms

The MKII version boasts has unveiled its latest innovation, , encompassing hundreds of new, used, and faulty valves. This upgrade significantly increases the device’s intelligence and testing capabilities. Moreover, the tester’s internal mechanisms generate and control all necessary voltages, enabling quick and efficient testing without excessive heat production.

Enhancements in the MKII model include a higher current capacity, advanced ‘grid leakage detection testing’, a novel ‘thermal runaway’ test, and a ‘digital microphony function’ for pre-amp valve testing. The device’s durable design and improved valve sockets further improve its reliability and ease of use.
