• KEEP THESE INSTRUCTIONS.
• HEED ALL WARNINGS.
• FOLLOW ALL INSTRUCTIONS.
• YOUR AMPLIFIER IS LOUD!
EXPOSURE TO HIGH SOUND VOLUMES MAY CAUSE PERMANENT HEARING DAMAGE !
Practice “safe listening.”
• No user serviceable parts inside. Refer service to qualified personnel. Always unplug AC
power before removing chassis.
• IF YOU INTEND ON OPERATING THIS EQUIPMENT OUTSIDE OF THE USA: Always insure
that unit is wired for proper voltage. Make certain all connections and grounding con-
forms with local standards. Make certain that you have obtained authorization to operate
prior to connecting to power supply.
• WARNING: Vacuum tube amplifiers generate heat. To insure proper ventilation always
make certain there is at least four inches (100mm) of space behind the rear of the amplifi-
er cabinet.
• Keep away from curtains or any flammable objects.
• WARNING: Do not block any ventilation openings on the rear or top of the amplifier. Do
not impede ventilation by placing objects on top of the amplifier which extend past the
rear edge of its cabinet.
• WARNING: Do not expose the amplifier to rain, moisture, dripping or splashing water. Do
not place objects filled with liquids on or nearby the amplifier.
• WARNING: Always make certain proper load is connected before operating the amplifier.
Failure to do so could pose a shock hazard and may result in damage to the amplifier.
• Do not expose amplifier to direct sunlight or extremely high temperatures.
• Always insure that amplifier is properly grounded. Always unplug AC power cord before
changing fuse or any tubes. When replacing fuse, use only same type and rating.
• Avoid direct contact with heated tubes. Keep amplifier away from children.
• Be sure to connect to an AC power supply that meets the power supply specifications
listed on the rear of the unit. Remove the power plug from the AC mains socket if the unit
is to be stored for an extended period of time. If there is any danger of lightning occurring
nearby, remove the power plug from the wall socket in advance.
• To avoid damaging your speakers and other music equipment, turn off the power of all
related equipment before making the connections.
• Do not use excessive force in handling control buttons, switches and controls. Do not
use solvents such as benzene or paint thinner to clean the unit. Wipe off the exterior with

Preparing to Operate your CLEAN SINK MKII™
Make certain that all connections are made prior to operating your CLEAN SINK MKII Amplifier in-
cluding power cable, speaker connection, instrument cable and instrument connection. Make certain
that all tubes are installed.
Power Switch (1)
The POWER switch, when placed in the UP position, provides AC wall power to the amplifier.
Standby Switch (2)
The STANDBY switch, when placed in the DOWN position, puts the amplifier in ‘standby mode’ allow-
ing the tubes to warm up.When this switch is place in the UP position, the tube circuitry is fully func-
tional and ready to amplify your guitar signal.
Hybrid-MASTER™ Control (3)
The Hybrid-MASTER control allows you to set the overall volume level of the amplifier without
changing the tone or feel of the amplifier. Hybrid-MASTER is a patented by 3rd Power.
Treble Damping Control (4)
The global TREBLE DAMPING control allows you to adjust the character or your high frequencies in-
dependent from your preamp section. Low settings are brighter. Rotating clockwise, ‘darker’ tones
tones will be achieved. This is important when considering that the Treble control in the preamp
dramatically affects the response (quickness or edge) of the preamplifier. When driving the amplifier
tones to edge of breakup, higher TREBLE DAMPING settings will make the amplifier smoother and
more vintage or silky sounding.
Reverb Control (5)
The REVERB control is used to add/blend in the perfect amount of ambience to your sound.The re-
verb effect in this amplifier features pure Class A vacuum tube drive and recovery circuitry to deliver
an authentic, vintage sounding spring reverb effect.

Input Jack (1)
The INPUT jack is where you connect instrument level signals.
AC Voice Switch (2)
The AC VOICE Switch allows you to choose between AC NORMAL and TOP BOOST modes. This
switch allows you to increase the gain and brightness character of the British AC tones only and
has no effect on the American voicing.
Volume Control (3)
The VOLUME control allows you to adjust the signal level as well as the temperament and over-
all character of your instrument’s sound, from clean to edge of breakup.
Voice Control (4)
The VOICE control allows you to select or blend the preamp voicing of your tone. When rotated fully
clock-wise, you will hear a pleasing mid-60’s black-panel American tone. when rotated fully counter
clock-wise, you will hear the distinct chime of a mid-60’s British tone. All other knob positions are
available to you to explore and create your own unique blended preamp tones.
Treble Control (5)
The TREBLE control allows you to adjust the character of the higher frequency range.
Bass Control (6)
The BASS control allows you to adjust the depth of your lower frequencies.

AC Fused Input (1)
The AC FUSED INPUT socket (TYPE IEC Grounded) is a required connection for operating your CLEAN
SINK MKII at 120V (standard USA household electrical power).The MAINS FUSE requires a 1.25 AMP
slow blow fuse.This fuse protects your amplifier from voltage peaks from your power outlet.
H.T. Fuse (2)
The H.T. FUSE requires a 0.25 AMP (250 milliamp) slow-blow fuse.The H.T. FUSE usually blows if your
power tubes are bad to protect the circuit from being damaged.
SAFETY NOTES:
• Always plug your amp into a properly grounded 3 prong AC outlet.
• Never plug your amp into an ungrounded outlet.
• Never remove or break off the 3rd prong safety ground pin from the power cord.
• Never use a damaged or ungrounded power cord.
• Always use the proper value and type fuse according to the rear-panel markings.
• Never attempt to replace the fuse while the amplifier is still plugged into the power source.The
fuse should only be replaced when the power cord has been disconnected from its power source.

8-OHM Speaker Outputs (3)
The 8-OHM SPEAKER OUTPUT is connected to the internal speaker via a short patch cable.
4-OHM Speaker Outputs (4)
The 4-OHM SPEAKER OUTPUTS are wired in parallel.They are provided for connecting your amplifier
to a single 4-OHM speaker, or two 8-OHM speaker cabinets.
OPERATIONAL NOTES:
• When operating an external 8-ohm cabinet along WITH the internal speaker, you will need to
remove the internal speaker patch cable from the 8-ohm jack and insert it into one of the 4-ohm
jacks and then connect the external cabinet to the remaining 4-ohm jack.
• REMEMBER to be sure and reconnect the internal speaker patch cable to the 8-ohm jack when
you return to operating only the internal speaker.
SAFETY NOTES:
• Never operate your amplifier without a connected speaker cabinet.This will damage your tubes
or transformers - or both.
• Always operate your amplifier with the proper impedance output that matches your speaker cab-
inet(s).
• In all cases, always use a good quality heavy gauge speaker cable (not a shielded instrument ca-
ble) to connect your CLEAN SINK to external speaker cabinet(s).

Bias Adjustment
Your CLEAN SINK MKII comes from the factory biased for JJ 6V6S tubes with an idle current draw of
~25ma. Bias adjustments are not intended to be user-serviceable. Attempting to adjust the bias your-
self will expose you to very dangerous high-voltage electricity that can kill you. Special test equip-
ment and knowledge of amp circuits and tubes are required to perform this function. DO NOT AT-
TEMPT TO DO THIS YOURSELF.
Tube Replacement
WE RECOMMEND TAKING YOUR AMPLIFIER TO A QUALIFIED TECHNICIAN FOR SERVICING YOUR
TUBES. Make certain the amplifier is turned off and has been allowed ample time to cool down. Be
very careful when you remove the tubes as they might still be very hot! Do not touch tube sockets
with fingers! Even after turning your amp off and unplugging it from the power outlet there could be
enough voltage stored in the capacitors to give you a lethal electrical shock.
WARNING:
• Do not remove the back panel.
• Do not attempt to check or replace tubes yourself. Refer to an authorized service center.
• Never touch the tubes while the amplifier is turned on or has recently been turned ON.You can
severely burn your fingers and hands.
