A. POWER RATING - Connect the power line cord to a
g rounded AC receptacle in accordance with the
voltage and frequency ratings shown on the Rear Panel
of the amplifier.
B. FUSE - Protects the amplifier from electrical faults.
Replace fuse only with same type and rating listed on
the fuse holder. If the amplifier repeatedly blows fuses,
take the amplifier to an authorized Fender Service
Center.
C . POWER SWITCH - Push UP to switch ON the amplifier.
Push DOWN to switch OFF the amplifier.
D. STANDBY SWITCH - Push DOWN to put the amplifier
into STANDBY mode. Push UP to put the amplifier into
normal OPERATING mode. In STANDBY mode, power
is supplied to the tube filaments only. This eliminates
w a rm-up time when re t u rning the amplifier to
OPERATING mode and also increases tube life span.
The POWER switch {C} must be ON for the STANDBY
switch to function.
E. MAIN SPEAKER JACK - Plug-in connection for
speakers. A speaker must always be connected at this
jack when the amplifier is ON.
F. EXTERNAL SPEAKER JACK - Plug-in connection for
an external speaker. This jack is wired in parallel with
the MAIN SPEAKER JACK {E}. A total speaker
impedance load of 4-ohms should be used to avoid
damage to the amplifier.
G. FOOTSWITCH JACK - Plug-in connection for the
FOOTSWITCH which enables ON/OFF switching of the
VIBRATO and REVERB effects. The VIBRATO effect
will not function without the FOOTSWITCH plugged in.

`65 Twin Reverb – Rear Panel
The tube BALANCE and BIAS of your ‘65 Twin Reverb is adjusted at the factory and should
provide years of service before needing attention. If the sound quality of the amp has degraded
noticeably and HUM BALANCE and BIAS adjustments fail to restore sound quality, the tubes
are worn and need replacement. Note that pre-amplifier tubes last longer than output tubes. If
you are not sure about the condition of your tubes or the following procedures, take your
amplifier to an authorized Fender Service Center.
A. HUM BALANCE ADJUSTMENT - This adjustment minimizes the hum heard at the speakers
due to tube filament imbalance. Balance is usually adjusted only when tubes have been
replaced. •Adjustment Instructions: Turn the amplifier ON for 2 minutes with nothing
plugged into any of the INPUTS. Rotate the VIBRATO CHANNEL volume, middle, and bass
knobs fully clockwise and the treble knob fully counter-clockwise. Rotate ALL of the
NORMALCHANNEL knobs fully counter-clockwise. Switch OFF the REVERB and VIBRATO
effects. Then insert a slotted screwdriver into the BALANCE ADJUSTMENT control, (see
“A” in FIG. 1) and rotate back and forth to the position with the least amount of hum.
B . BIAS ADJUSTMENT - This adjustment only should be made if the output tubes are
replaced with tubes not identical to the original tubes and should be adjusted only by an
authorized Fender Service Center.
