Using Your Amplifier IMPORTANT! 1. 2. Before connecting your amplifier to a power source, please check the following: Ensure your speaker cabinet is connected to the correct impedance speaker output socket, (see Rear Panel, item 2), using a good quality speaker cable. Do not use guitar leads. Ensure that the voltage selector switch is set to the correct mains voltage, (see Rear Panel, item 5).
WARNING VALVES AND FUSES CAN FAIL AT ANY TIME! From time to time output and preamp valves may fail. Most users find regular valve replacement to be of benefit to the general upkeep and reliability of their amplifier. We suggest that you always have spare valves available as replacements in the event of a valve failure. Every Orange Class AB Amplifier will require re-biasing when it’s output valves are replaced. This may not be necessary if use the same brand of valves with a similar manufacturers rating.
