M. POWER CORD - Connect the power line cord to a
grounded AC outlet in accordance with the voltage
and frequency ratings listed on the rear panel of your
amplifier.
N. FUSE - Replace a failed fuse ONLY with the type and
rating as labeled on the fuse holder.
O. POWER - Switches the amplifier on and off.
P. STANDBY - Use STANDBY during short breaks
instead of switching the amplifier off . By doing this
you avoid the warm-up delay upon returning to play
and you extend the life span of your tubes. Using
STANDBY for 30 seconds when first switching the
amplifier on will also extend tube life span.
Q. SPEAKER - Main speaker connection. A speaker
must ALWAYS be connected at this jack when the
amplifier is on to prevent damage to the amplifier.
R. EXTERNAL SPEAKER - Connection for an external
speaker. Only plug an 8-ohm speaker into this jack
when there is another 8-ohm speaker connected to
the main SPEAKER jack.
S. FOOT PEDAL - Connect the included foot pedal
here to enable remote on/off switching of Reverb and
Vibrato.

If the sound quality of the amp has degraded noticeably the tubes may be worn and need replacement. Output tubes
typically need replacement before pre-amp 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. Replace tubes with identical Fender® original
equipment only (see SPECIFICATIONS below). Tube location is printed on the tube label, inside the cabinet.
T. HUM BALANCE ADJUSTMENT - This adjustment minimizes the hum heard at the speakers due to tube filament
imbalance. •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 Normal channel knobs fully counter-clockwise. Switch OFF the
REVERB and VIBRATO effects. Insert a slotted screwdriver into the BALANCE ADJUSTMENT control {T} and
rotate back and forth to the position with the least amount of hum.
U. BIAS ADJUSTMENT - This adjustment should be made only by an authorized Fender Service Center. BIAS
needs adjustment only if the replacement output tubes are not identical to the original tubes.
