‘65 TWIN REVERB REAR PANEL FUNCTIONS
A. GROUND SWITCH -
Set the GROUND SWITCH to the position that produces the least amount of “buzz” or “hum” from the
speakers.
B. 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.
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 speakers. 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 conjunction 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 that only the REVERB feature will operate
without plugging in the footswitch.
H. VIBRATO SWITCH-Push
on, push off switch that turns the VIBRATO feature on and off.
