The new Orange Valve Tester MKII will undoubtedly come in handy for anyone with tube equipment that may need a tube replacement at some point.
Measuring tubes normally requires expert knowledge. But unlike in the past, where you had to turn the knobs and interpret the data yourself, nowadays this is much easier. This is clearly shown by the new Orange Valve Tester MKII. This device measures and judges tubes fully automatically. Everything is based on a microcontroller that performs a series of complex inter-electrode switches and loads and measures the tube too. You don’t really need any further knowledge. It’s just a matter of plugging in a tube and pressing the OK button. The British manufacturer promises that then the verdict is quickly displayed.
More test options
Compared to its predecessor, the Orange Valve Tester MKII has a significantly larger database of tubes and tube data. Also new are a high current grid leaking test, a thermal runaway test and a digital microphony function test. The latter is specifically intended for preamplifier tubes. Should you want even more, there is an optional expansion module. This allows you to directly directly heated tubes like the 300B and others like the EF86 and GZ34. Ideal for audiophile hi-fi enthusiasts, then.
