USING YOUR AMPLIFIER
IMPORTANT! Before connecting your amplifier to a power source, please check the following:
1. 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.
2. The output (HALF/STBY/FULL) switch (found next to the power switch on front of amplifier) runs
the valves at a low plate voltage (reducing output power) in the HALF position and at a higher plate
voltage (increasing output power) in the FULL position. The middle position is the standby position.
Make sure that the HALF/STBY/FULL output switch is in the Standby (middle) position before
switching the power switch to the ON position (this will maximise the life of your valves). If you are
unsure about any of the above points please consult your local Orange supplier.
