Orange introduces Valve Tester MKII

Orange Amplification has unveiled its Orange Valve Tester MKII, which supersedes the company’s VT1000. Made and designed in the UK, it boasts a microprocessor-controlled testing system carrying out a series of inter-electrode switching and measurement exercises.

The company claims no prior knowledge of valve theory is needed to use the MKII: “the 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 is quickly revealed.”

The Valve Tester is said to feature: “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 with 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.”

In addition, the new unit features higher current capacity with enhanced ‘grid leakage detection testing’, a new ‘thermal runaway’ test and a ‘digital microphony function’ to test preamp valves. Its updated design also features improved sockets.

The Orange Valve Tester MKII allows the testing of directly heated valves such as the 300B and other valve types including EF86 and rectifier valve GZ34.
