R. POWER - Switches power ON and OFF to the
amplifier. (Reduce the “shock” to amplifier tubes at
power-up, extending their life span, by turning the
amp ON with the STAND BY switch DOWN for the
first minute, then UP for normal use.
S. STAND BY - In the DOWN position, this switch puts
the amp on stand by. Audio is muted and power is
supplied only to the tube filaments. Use STAND BY
in place of switching POWER OFF during short
breaks (one hour max.). This eliminates the normal
warm-up time when STAND BY is switched OFF (UP)
when returning to play the amplifier and also extends
the life span of your amplifier’s tubes.
T. IEC LINE CORD CONNECTO R - Connect the
supplied IEC POWER LINE CORD to a grounded AC
receptacle in accordance with the voltage and fre q u e n c y
ratings as shown on the rear panel of the amplifier.
U. FUSE - Power Mains fuse, protects the amplifier
from electrical faults. Replace a failed fuse only with
the proper type and rating (See FUSE F200 under
“Specifications”). If a fuse repeatedly fails, consult
an authorized Fender service technician.
V. OUTPUT POWER - Selects amplifier output power:
• • FULL (50 watts), or • • 1/4 (12.5 watts).
Note: See “Effects Loop Settings” on the next page for
details on the use of items (W—AA).
W. SEND - Controls the SEND jack output level.
X.
SEND JACK - Output jack for connection to the
input jack of effects devices in an effects loop.
Y. LOOP - This two position button engages/bypasses
the effects loop:
button OUT > to BYPASS the effects loop
button IN > to ENGAGE the effects loop
*Note: When the Footswitch is plugged into the
FOOTSWITCH jack, effects LOOP BYPASS/ENGAGE
are possible only from the Footswitch.
Z. RETURN JACK - Input jack for connection to the
output jack of an effects device in an effects loop.
AA. RETURN - Controls the RETURN jack input level
going into the power amp.
BB. PRE AMP OUT JACK - This output jack supplies
an unbalanced, line-level signal (with Reverb) to a
re c o rding/sound re i n f o rcement console, or to an
external power amplifier such as another Pro-Tube
amplifier used as an extension amp.
CC. POWER AMP IN - This input jack connects directly
to the power amplifier, automatically disconnecting
the preamp signal from the circuit. When using your
Pro-Tube as an extension amp, connect the PRE-
AMP OUT jack on another Pro-Tube amp, to this
jack. Control both units from the source amplifier.
DD. F O OT S W I TC H JACK - Connect the supplied
4–button Footswitch at this jack to enable these
Footswitching functions:
• • SELECT Pre-Amp Channel*
• • BYPASS/ENGAGE the Effects Loop*
• • Switch Tremolo ON/OFF
• • Switch Reverb ON/OFF
*Note: When the Footswitch is plugged into the
FOOTSWITCH jack, CHANNEL SELECTION and
effects LOOP BYPASS/ENGAGE are possible only from
the Footswitch.
EE.—JJ. (See “Tube Adjustment” on the next page.)
KK. EXTERNAL SPEAKER JACK - Connect an 8 ohm
external speaker cabinet at this jack only if another
8 ohm speaker load is connected at the M A I N
SPEAKER jack (see MAIN SPEAKER jack and “Speaker
Connection Guide” below).
Note: When a plug is inserted in the EXTERNAL
SPEAKER jack, the amplifier is automatically switched
to handle a 4 ohm speaker load.
LL. MAIN SPEAKER JACK - Keep the intern a l
speakers connected at this jack for normal amplifier
operation (8 ohm load).
I M P O R TA N T !: SPEAKERS MUST ALWAYS BE
CONNECTED AT THE MAIN SPEAKER JACK WHEN
THE AMPLIFIER IS SWITCHED ON TO PREVENT
SERIOUS DAMAGE TO THE AMPLIFIER!
Speaker Connection Guide
Connect speakers to MAIN SPKR and EXT SPKR jacks using
these configurations:
M A I N EXTERNAL P R O P E R
SPEAKER J A C K 1 SPEAKER J A C K L O A D
I n t e rnal 8 ohm + N O N E = 8 ohms
E x t e rnal 8 ohm + N O N E = 8 ohms
I n t e rnal 8 ohm + E x t e rnal 8 ohm = 4 ohms 2
E x t e rnal 8 ohm + E x t e rnal 8 ohm = 4 ohms 2

SPEAKER jack, the amplifier is automatically switched to
handle a 4 ohm speaker load.
