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.

Orange Valve Tester mk2

I found the tester really easy to use and it helped quickly identify microphonics in a batch of old tubes I had, I could easily check power valves pairing, and identify those 'hotter' pre-amp tubes.

The only reason for giving four stars is the price - but these aren't going to be sold in large volumes, and if you test enought valves, or have multiple amps, it's worth the investment.

Hi Michael,

Thank you for taking the time to leave us a review - we really appreciate it!

Valve Tester Mk2

Like all Orange gear it’s exactly as expected and this valve tester is easy to use, fast process of the test within a cpl mins, outstanding. Another great use , I will be taking is compact unit with me whenever purchasing Valves from a private seller ( unused vintage stocks of Hi-Fi tube collectors that need to sell )& get a value/rating without concerns or relying solely on faith. Got some great 1970’s tubes , unused and 1/3 price of new issues. 👍👍 from me.

Thanks so much for taking the time to leave us a review - we really appreciate it Mark! Glad to hear you're loving your Valve Tester.

Valve tester

I haven't had much chance to use it but checked all the valves I have here at home. Service was great. It arrived so fast I was wondering what it was.
I got all the valves matched up now that's a great feature

Hey Carter, thanks so much for taking the time to leave us a review - we really appreciate it! Glad you were happy with the speedy delivery :)
