Attenuator – Set the Wattage toggle to the right for full 18 watts with the speaker bypassing
the attenuator. With the Toggle baton left the Attenuator is engaged for a maximum of 6
watts output.
Standby – Off – Play – The Toggle switch baton in the middle position is Power Off. To
play set the amp to Standby (switch baton down). After 1 minute of warm up, switch the
Power baton up to Play.The amp is ready to be played. Using the Standby setting every time
the amp is turned on will prolong tube life. Note: When turning amp off with Channel set to
Overdrive you will hear a ‘Thump’ as the relays cycle – this is normal and will only be
audible when set to OD at turn off. If amp is on the Clean channel at turn off there will be
no relay ‘Thump’. The relay cycle will not hurt the amp.

Fuse –In the unlikely event that a tube fails, the Lincoln 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 behind the power tubes on the
chassis (see Chassis Diagram). The Lincoln is designed to drive an 8 ohm load. Maximum
tone will be realized when connected to a 8 ohm speaker or cabinet. The speakers in Lincoln
combos are configured to provide the amplifier with an 8 ohm load.
To run an external cabinet, turn the Lincoln 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 Lincoln without a speaker load.
Biasing your Carr Lincoln
The Lincoln is a cathode bias (self bias) amplifier and as such does not require a bias
adjustment when changing tubes. Please use matched pairs of output tubes for maximum
performance. The Lincoln can only use matched pairs of EL-84 power tubes.
Carr Amplifiers selects and tests the finest current production tubes specifically for each
amplifier model. Caution should be used when buying replacement tubes from any dealer
who does not have a return policy as all tubes can have problems (NOS tubes are
susceptible to microphonics and failure too).
