AC POWER INLET:
13
This is the receptacle for an IEC line cord, which provides AC power to the unit. Connect the line cord to
this connector to provide power to the unit. Damage to the equipment may result if improper line voltage
is used. (See VOLTAGE SELECTOR SWITCH #12).
Never break off the ground pin on any equipment. It is provided for your safety. If the outlet used does not
have a ground pin, a suitable grounding adapter should be used and the third wire should be grounded
properly. To prevent the risk of shock or fire hazard, always make sure that the amplifier and all associated
equipment is properly grounded.
Note for UK ONLY
As the colors of the wires in the mains lead of this apparatus may not correspond with the colored
markings identifying the terminals in your plug, proceed as follows: (1) The wire that is colored green and
yellow must be connected to the terminal that is marked by the letter E, or by the Earth symbol, or colored
green or green and yellow. (2) The wire that is colored blue must be connected to the terminal that is
marked with the letter N, or the color black. (3) The wire that is colored brown must be connected to the
terminal that is marked with the letter L, or the color red.
To avoid the risk of electrical shock, do not place fingers or any other objects into empty tube sockets
while power is being supplied to unit.
FUSE
14
The fuse is located within the cap of the fuseholder. If the fuse should fail, IT MUST BE REPLACED WITH THE
SAME TYPE AND VALUE IN ORDER TO AVOID DAMAGE TO THE EQUIPMENT AND TO PREVENT VOIDING THE
WARRRANTY. If the amp repeatedly blows fuses, it should be taken to a qualified service center for repair.
WARNING: THE FUSE SHOULD ONLY BE REPLACED WHEN THE POWER CORD HAS BEEN DISCONNECTED
FROM ITS POWER SOURCE.
POWER OUTPUT SWITCH
15
This three position switch controls an attenuator which allows the maximum output of the amplifier to be
switched between 100%, 25% and 5% of rated power. Therefore, between 20 watts, 5 watts and 1 watt.
This enables the user to drive the power stage hard, therefore producing the characteristic power amp
overdrive, but without such loud volumes being produced by the speaker.
