Preparing to Operate your Dream Single Channel Amplifier

Make certain that all connections are made prior to operating your Amplifier including 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 DOWN position, provides AC wall power to the amplifier.

Standby Switch (2) 

The STANDBY switch, when placed in the UP position, puts the amplifier in ‘standby mode’ allowing 
the tubes to warm up. When this switch is place in the DOWN position, the tube circuitry is fully 
functional and ready to amplify your guitar signal.

HybridMASTER™ (3)

The HYBRID MASTER control allows you to set the overall volume level of the amplifier independ-
ent of the volume and tone settings established on the front panel. Think of this as a “micro” volume 
adjustment. When turned all the way up (full clock-wise rotation), HybridMASTER is completely re-
moved from the circuit. HybridMASTER is patent-pending.

Stage/Studio Switch (4)

The STAGE/STUDIO MODE switch allows you to operate the amp at full volume (Stage mode) or at 
an 80% reduction in volume (Studio mode). Think of this as a “macro” volume adjustment.

Presence Control (5)

The PRESENCE control allows you to adjust the character or ‘forwardness’ of your sound. Low set-
tings create ‘darker’ tones, whereas higher settings create a ‘brilliant’ or crisp sound. 

NOTE: that the PRESENCE control is not included on the Dream 40 AC model.

• NORMAL: Wide, full range of frequencies.
• BRILLIANCE: Adds high frequency emphasis on top of the full range response of NORMAL mode.
• TOP BOOST 1:  Gentle roll-off of low and low mid frequencies with extended upper mid-range. 
• TOP BOOST 2:  Dramatic roll-off of low and low mid frequencies with even greater emphasis of 

upper mid-range and high frequencies.

Mid Contour Switch(9)

The MID CONTOUR switch allows you to toggle between two mid-range frequency response curves. 
In the down position, you’ll hear the classic early 60’s AC tone stack with it’s chimey mid-scoop con-
tour. In the UP position, you’ll hear a modern “post 2000” mid forward contour.

Top Cut Control (10)

The TOP CUT control allows you to adjust the tonal emphasis of your high frequencies.

AC Input (22)

The AC INPUT socket (TYPE IEC Grounded) is a required connection for operating the unit at 120V 
(standard USA household electrical power). 

Mains Fuse (23)

The MAINS FUSE requires a 2 AMP fast-acting fuse. This fuse protects your amplifier from voltage 
peaks from your power outlet.  

H.T. Fuse (24)

The H.T. FUSE requires a .3 AMP (300 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.

16-OHM Speaker Output (25)

The 16-OHM SPEAKER OUTPUT is provided for connecting your amplifier to standard 16 OHM 
speaker cabinet.

8-OHM Speaker Outputs (26)

The 8-OHM SPEAKER OUTPUT is provided for connecting your amplifier to standard 8 OHM speaker 
cabinet.

4-OHM Speaker Outputs (27)

The 4-OHM SPEAKER OUTPUT is provided for connecting your amplifier to standard 4 OHM speaker 
cabinet.

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 

cabinets(s). 

• In all cases, always use a good quality heavy gauge speaker cable (not a shielded instrument 

cable) to connect your Dream Amplifier to the speaker cabinet(s).

Effects Insert (28)

The EFFECTS INSERT is designed to allow you to insert an effects device (most often, time-based 
effects like delay or reverb) after the preamp and before the power amp. When no effects device is 
present, this circuit is completely bypassed to deliver a direct signal path between the preamp and 
power amp stage. For best results, utilize professional type effects processors with at least +15dBu 
input sensitivity.

OPERATION NOTES:

• This is a line-level effects insert that is best suited for professional rack-mount effects devices 

capable of handling up to 4.5Vrms. 

• Best performance is achieved by minimizing patch cable length.
• When cable runs are over 5 - 10 feet it may be beneficial to use an external effects buffer device 

on the SEND connection.

Tube Layout and Requirements:

V1 and V2: JJ 12AX7 (Preamp)
V3: Sovtek 12AX7LPS (Phase Inverter)
V4 and V5: EL34 or 6L6GC output tubes
V6: Rectifier tube socket
• Model Dream 40 American and Dream 40 AC loaded with GZ34 Tube Rectifier
• Model Dream 50 Plexi loaded with Diode Rectifier Adapter

Bias Adjustment

Your Dream Amp comes from the factory biased for EL34 or 6L6GC tubes. Bias adjustments are not 
intended to be user-serviceable. Attempting to adjust the bias yourself will expose you to very dan-
gerous high-voltage electricity that can kill you. Special test equipment and knowledge of amp cir-
cuits and tubes are required to perform this function. DO NOT ATTEMPT 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.
