Orange Amplification is excited to present the Orange Valve Tester MKII, surpassing the Orange VT1000 as the world's premier automatic digital valve tester, a pioneering innovation developed and patented by Orange.

Crafted and engineered in the UK, the Orange Valve Tester MKII executes a broad spectrum of tests with unparalleled speed, ease, and precision, establishing a new global benchmark in valve-testing technology for both hi-fi aficionados and service experts.

Despite its straightforward operation, the device houses a complex microprocessor-controlled testing system that performs intricate inter-electrode switching and measurement tasks. Users, without needing any understanding of valve theory, can simply place a valve into the appropriate socket, select the valve type from the provided list, and press the 'OK' button to promptly ascertain the valve's condition.

The latest iteration of the Orange Valve Tester boasts significantly enhanced algorithms and an expanded database, cataloging test outcomes for a vast array of new, used, and defective valves, endowing the MKII with superior intelligence relative to the original Orange VT1000. The tester's voltages are internally generated, stabilized, and regulated, facilitating swift static and dynamic testing without generating excess heat.

Moreover, the updated model offers increased current capabilities, advanced 'grid leakage detection testing,' a novel 'thermal runaway' assessment, and a new 'digital microphony function' for evaluating pre-amp valves. It also features a more robust design and improved valve sockets.
