PRECAUTIONS & WARNINGS
• READ THESE INSTRUCTIONS.
• 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 ampli-
fier 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
soft cloth.

Preparing to Operate your American Dream™
Make certain that all connections are made prior to operating your
American Dream™ Amplifier including power cable, speaker connec-
tion, 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 CENTER position, puts the
amplifier in ‘standby mode’ allowing the tubes to warm up. When this
switch is place in the UP position, the tube circuitry is fully functional
and operating in 40W(pentode) mode. In the DOWN position, the am-
plifier is operating in 20W(triode) mode.
Presence Control (3)
The global PRESENCE control affects both channels and allows you to
adjust the character or ‘forwardness’ of your sound. Low settings cre-
ate ‘darker’ tones, whereas higher settings create a ‘brilliant’ or crisp
sound.

Input Jack (4)
The INPUT jack is where you connect instrument level signals.
Bright Switch (5)
The BRIGHT SWITCH allows you to emphasize the higher frequen-
cies of your sound.
Volume Control (6)
The VOLUME control allows you to adjust the signal level as well as
the temperament and overall character of your instrument’s sound.
The Brownface channel has been optimized to provide superb versatility
with a particular emphasis on mid-range frequencies.
Tone Control (7)
The TONE control of the Brownface channel allows you to adjust the
tonal emphasis of your sound from ‘dark’ to ‘bark’. This control also
works in conjunction with the VOLUME control and will have a subtle
yet substantial affect on the level of perceived instrument gain.

Bright Switch (9)
The BRIGHT SWITCH allows you to emphasize the higher frequen-
cies of your sound.
Volume Control (10)
The VOLUME control allows you to adjust the signal level as well as
the temperament and overall character of your instruments sound. The
Blackface channel has been optimized to provide superb versatility with
a particular emphasis on refining the mid-range frequencies to deliver a
fuller, or ‘wider’ sounding tone.
Treble Control (11)
The TREBLE control allows you to adjust the character of the higher
frequency range. The TREBLE circuitry has been optimized to deliver
excellent high frequency character while retaining a smooth tempera-
ment.
Bass Control (12)
The BASS control allows you to adjust the depth of your lower fre-
quencies. The BASS circuitry has been optimized to provide deep, rich
low frequencies.

AC Input (13)
The AC INPUT socket (TYPE IEC Grounded) is a required connec-
tion for operating your AMERICAN DREAM™ at 117V (standard
USA household electrical power).
Mains Fuse (14)
The MAINS FUSE requires a 3 AMP fast-acting fuse. This fuse pro-
tects your amplifier from voltage peaks from your power outlet.
H.T. Fuse (15)
The H.T. FUSE requires a 1 AMP slow-blow fuse. The H.T. FUSE
usually blows if your power amp tubes are bad to protect the circuit
from being damaged.
SAFETY NOTES:
1) Always plug your amp into a properly grounded 3 prong AC out-
let.
2) Never plug your amp into an ungrounded outlet.
1) Never remove or break off the 3rd prong safety ground pin
from the power cord.
1) Never use a damaged or ungrounded power cord.
2) Always use the proper value and type fuse according to the rear-
panel markings.
3) Never attempt to replace the fuse while the amplifier is still
plugged into the power source. The fuse should only be re-
placed when the power cord has been disconnected from its
power source.

16-OHM Speaker Output (16)
The 16-OHM SPEAKER OUTPUT is provided for connecting your
amplifier to standard 16 OHM speaker cabinet.
8-OHM Speaker Output (17)
The 8-OHM SPEAKER OUTPUT is provided for connecting your
amplifier to single 8-OHM speaker, such as the internal speaker for the
combo unit.
4-OHM Speaker Outputs (18)
The two (2) 4-OHM DISCREET SPEAKER OUTPUTs are provided
for connecting your amplifier to single 4-OHM speaker cabinet or for
connecting two (2) 8-OHM speaker cabinets in parallel.
SAFETY NOTES:
1) Never operate your amplifier without a connected speaker cabi-
net. This will damage your tubes or transformers - or both.
2) Always operate your amplifier with the proper impedance out-
put that matches your speaker cabinets(s).
3) In all cases, always use a good quality heavy gauge speaker cable
(not a shielded instrument cable) to connect your AMERICAN
DREAM to the speaker cabinet(s).

HybridMASTER™ (16)
The HYBRID MASTER control allows you to set the overall volume
level of the amplifier independent of the volume and tone settings es-
tablished on the front panel. This is a patent-pending circuit design
developed by 3rd Power and is available exclusively on Dream and
Dream Solo series amplifiers.
Things to Try
• “40 Watt” Mode with HybridMASTER set to 50% will reduce the
volume in half while retaining the tone and feel of the amplifier.
• “20 Watt” Mode with HybridMASTER set to 50% will reduce the
volume by 75% while retaining the tone and feel of the amplifier.
