Orange Amplifiers Valve Tube Tester MKII

The Orange Valve Tester MKII automatically tests Hi-Fi/guitar amplifier valves and displays their condition, performing a wide range of tests, quickly and accurately. This revolutionary valve-testing technology sets a new global standard for both Hi-Fi enthusiasts and service professionals.

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.

In addition, the new unit features higher current capacity with enhanced 'grid leakage detection testing', a new 'thermal runaway' test and a new 'digital microphony function' to test pre-amp valves. Its new rugged mechanical design and form also has improved valve sockets.

- Microphony test (ECC81, ECC82, ECC83 & 12BH7 only)
- Capability to test directly heated valves with expansion modules
- All valves tested under higher current
- Improved test sockets
- More rugged design
- Capability to test other valve types such as rectifiers with expansion modules
- Valve failure mode fault
