Designed & Made in the UK

The Orange Valve Tester MKII, proudly crafted and engineered in the UK, revolutionises valve-testing technology. With seamless precision and simplicity, it effortlessly conducts a comprehensive array of tests, setting a new global standard for both Hi-Fi enthusiasts and service professionals.

  • Complexity made simple

    The simplicity of operation belies the complexity of what happens inside the unit during each test. Inside is a sophisticated microprocessor controlled testing system carrying out a series of complex inter-electrode switching and measurement exercises. Requiring no knowledge of valve theory a user simply inserts a valve into the correct socket, selects the valve type from the list and presses the OK button. The status of the valve under test is quickly revealed.

  • Portable and Convenient

    The Orange Valve Tester MKII is a sophisticated, simple to use, stylish and portable unit. Its usefulness has been designed to meet the needs of both seasoned audiophiles and those new to testing valves. The device’s fully automatic testing and matching capabilities ensure optimal valve performance across a wide range of audio valve equipment allowing users to effortlessly maintain quality, maximum performance and limit possible distortion of their Hi-Fi amplifier caused by substandard, worn or faulty valves.

  • New and Improved

    The latest model of the Orange Valve Tester has greatly improved algorithms with an updated database containing the test results of literally hundreds of new, used and faulty valves giving the MKII a much greater intelligence compared to the original Orange VT1000. All the voltages required by the tester are internally derived, stabilised and controlled allowing a rapid static and transient testing without unnecessary heat generation.
