Bottom Panel - Carr Rambler Amp Owner's Manual

equipment (a microphone or another amp) that is not properly grounded, or if you hear
static, switching to the opposite ON may solve the problem. This is sometimes called
"switching polarity".

–
Fuse In the unlikely event that a tube fails, the Rambler is protected by a 1.5 Amp slow
blow fuse for 120v and 100v (North America and Japan) models or a 0.75 Amp slow blow
fuse for 220v and 240v (Europe and Asia) models. Please consult us or a qualified tech for
assistance in the event of a fuse blowing. The fuse is located on the bottom of the chassis by
the power cord.
Speaker output jack – The speaker output jack is located between the power tubes on the
speaker side of the chassis (see Chassis Diagram). The Rambler is designed to drive an 8
ohm load. Maximum power and tone will be realized when connected to an 8 ohm speaker
or cabinet. The speakers in Rambler combos and extension cabinets are configured to
provide the amplifier with an 8 ohm load.
The Rambler will work with a 16 or 4 ohm cabinet with the following caveat - you will lose
a little power from the impedance mismatch, and the power tubes will have to work a bit
harder and thus age faster.
To run an external cabinet, turn the Rambler OFF, unplug the internal speaker (combo amps)
and plug in the external cabinet's speaker cord. Alternatively, a "Y" speaker cord can be
used to run an 8 ohm external cabinet along with the internal speaker(s) of a combo amp
without damage to the amp (the total impedance or speaker load in this case will be 4 ohms
– see the previous paragraph).
Damage will result from operating the Rambler without a speaker load.
Footswitch Jack – The tremolo can be turned on and off using the footswitch included with
the Rambler. The jack for the footswitch is on the bottom of the chassis between the third
and fourth preamp tubes (see Chassis Diagram).
