IEC POWER CORD SOCKET — Connect the included power
cord to a grounded A/C electrical outlet in accordance with
the voltage and frequency ratings specified on the rear panel
of your amplifier.

POWER SWITCH — Switch to the "ON" position to turn pow-
er on to the amplifier. Switch to the "OFF" position to turn
power off to the amplifier.
M. INTERNAL SPEAKER JACK — Plug-in connection for the 8Ω
internal speaker. When using only the internal speaker jack,
a speaker impedance load of 8Ω minimum must be used to
avoid distortion and damage to the amplifier.
A speaker must ALWAYS be connected to this jack when
!
POWER is switched "ON" to avoid possible damage to the
amplifier. Switch POWER to the "OFF" position while chang-
ing speaker connections.
N. EXTERNAL SPEAKER JACK — Plug-in connection for an ex-
ternal speaker. This jack is wired in parallel with the INTERNAL
SPEAKER jack {M} and affects the total speaker impedance
load. Use 8Ω minimum total (two 16Ω speakers = 8Ω total).
To connect external speaker cabinets:
1.
Switch POWER to the "OFF" position.
2.
Disconnect the internal speaker cable from the INTERNAL
SPEAKER JACK {M}.
3.
Connect one 16Ω external speaker to the INTERNAL
SPEAKER jack {M} and another 16Ω external speaker to the
EXTERNAL SPEAKER jack {N}.

Your new Fender® amplifier comes equipped with the highest
quality tubes available, designed and tested for use in the
demanding world of musical instrument amplification.
In most critical applications, we select Groove Tubes® preamp
and performance-matched power tube sets. Please make note
of the specific tubes used in each location in your amplifier
and write down the information in this manual for your future reference.
In particular, please locate and note the rating information on the base
of the power tubes. You may find this extremely useful if purchasing a
spare set for backup, or when replacing power tubes.
If you replace power tube sets with the same rating and type of Groove
Tubes, no adjustment should be needed. If you decide to tweak the
performance characteristics of your amplifier with a different power
tube set, you should have a qualified service technician re-bias your
amp to meet the optimum performance specifications for the new tubes.
In the future, if you experience any sonic performance issues with your
amp, or have further questions concerning the tubes in your amplifier,
please contact your Fender dealer or authorized service center.
Additional information concerning specific tube types, characteristics and
performance may be found at
