VALVES AND FUSES CAN FAIL AT ANY TIME! 

From time to time output and preamp valves may fail. We suggest that output valves are changed at 

least once a year and that all class AB models (50 watts and above) will benefit from having the bias 

checked and adjusted. Bias checking must be carried out by a qualified engineer. 

Orange amps are protected from damage caused by valve failure and inconsistent mains voltage by 

various fuses. We recommend that Orange users have a set of spare valves and fuses.
