‘63 VIBROVERB REAR PANEL FUNCTIONS

A.FUSE - The fuse is in the AC supply of the amplifier and will help to protect the amplifier and operator in the event of an electrical fault. If a fuse blows, it should only be replaced with a fuse in accordance with the listing at the fuse holder. If the amplifier repeatedly blows fuses, it should be checked out by a qualified technician. UNDER NO CIRCUMSTANCES should a fuse of a different type, higher current rating, or a fuse bypass be used, as this could damage the equipment and present a serious safety hazard.

B.GROUND SWITCH - The GROUND SWITCH is not functional, and is there to preserve the original appearance of the amplifier. The switch is not present in 100V, 230V, and 240V units.

C.POWER SWITCH - This switch turns the AC power ON and OFF. When the switch is OFF, the amplifier is completely shut down.

D.STANDBY SWITCH - This switch turns the amplifier on and off. In the STANDBY position, the amplifier is off; however, power is applied to the tube filaments so as to eliminate warm-up time. Use of this feature during short breaks versus using the POWER SWITCH will increase tube life.

E.MAIN SPEAKER JACK - Plug-in connection for speak- ers. This jack must always be used as the primary connection to speakers.

F.EXTERNAL SPEAKER JACK - Plug-in connection for an external speaker. This jack is wired in parallel with the MAIN SPEAKER JACK, and must only be used in con- junction with the MAIN SPEAKER JACK. Should the EXTERNAL SPEAKER JACK be used without also using the MAIN SPEAKER JACK, there will be no sound. Note that the amplifier is optimized for a 4 ohm speaker load, and that the speakers in the cabinet are wired for 4 ohms. Should a total load of more or less than 4 ohms be used, the amplifier will not put out its maximum power output before distortion occurs.

G.FOOTSWITCH JACK - Plug-in connection for the footswitch. The footswitch allows you to turn the VIBRATO and REVERB features on and off without having to operate the controls on the front panel. NOTE: The VIBRATO and REVERB features will oper- ate without plugging in the footswitch.
