HOUSE FOR VERIFICATION.
• DO NOT REMOVE SCREWS ON BOTTOM OF UNIT. LETHAL VOLTAGES LURK INSIDE. BOO!
CONTACT THE MANUFACTURER FOR SERVICE INFORMATION. SERVICE MUST BE PERFORMED BY
QUALIFIED PERSONNEL, NOT YOUR COUSIN WHO WIRED YOUR BASEMENT.
• THIS AMPLIFIER IS CAPABLE OF PRODUCING HIGH SOUND PRESSURE LEVELS. YEAH! CONTINUED
EXPOSURE TO HIGH SOUND PRESSURE LEVELS CAN CAUSE PERMANENT HEARING IMPAIRMENT OR
LOSS. WHAT’? USER CAUTION IS ADVISED AND EAR PROTECTION IS RECOMMENDED IF UNIT IS
OPERATED AT HIGH VOLUME, WHICH OF COURSE IT SHOULD BE.
• WHEN POWERED ON, THE TUBES MAY BECOME VERY HOT, HOT ENOUGH TO BURN SKIN ON
CONTACT. SO DON’T TOUCH ‘EM. AND KEEP OUT OF REACH OF CHILDREN AND PETS.
• DO NOT OPERATE WITHOUT SPEAKER OR OTHER SUITABLE LOAD CONNECTED TO THE SPEAKER
JACK, AS DAMAGE TO THE AMPLIFIER AND YOUR REPUTATION MAY RESULT.
• DO NOT OPERATE NEAR ANY HEAT SOURCE, ESPECIALLY A SWEATY ONE.
• DO NOT OPERATE WITH VENTILATION OPENING(S) COVERED, AS THIS MAY OVERHEAT THE
AMPLIFIER. DUH.
• DO NOT USE NEAR SPLASHING, FALLING, SPRAYING, OR STANDING LIQUIDS. AND DON’T EVER
LET SOME FOOL SET HIS DRINK ON YOUR RIG.
• CLEAN ONLY WITH A LINT-FREE DRY CLOTH. DO NOT USE CLEANING AGENTS. WHO CLEANS THEIR
AMP, ANYWAY?
• CONNECT POWER CORD ONLY TO A POLARIZED, SAFETY GROUNDED OUTLET WIRED TO CURRENT
ELECTRICAL CODES AND COMPATIBLE WITH VOLTAGE, POWER, AND FREQUENCY REQUIREMENTS
STATED ON THE APPLIANCE. THIS MEANS YOU.
• PROTECT THE POWER CORD FROM DAMAGE DUE TO BEING WALKED ON, PINCHED OR STRAINED.
IF YOU SMELL AN ELECTRICITY LEAK, CALL THE AUTHORITIES IMMEDIATELY.
• UNPLUG THE APPARATUS DURING LIGHTNING STORMS, WHEN NOT IS USE OR FOR LATE-NIGHT
SILENT OPERATION.

FRONT PANEL CONTROLS AND FEATURES, Right to Left
INPUT
Standard 1/4” guitar input jack.
NORMAL VOL, BRIGHT VOL & BRT/LINK/NORM Switch
The switch gives you the channel options
available on an original 4-input plexi. Choose the Normal Channel, Bright Channel or both channels
internally linked.
BASS, MID & TREBLE
Tone-shaping controls.
MASTER VOL
Post-phase inverter (PPI) Master Volume. Distortion can be obtained at any volume
by setting NORMAL VOL and/or BRIGHT VOL high enough to overdrive the preamp, and setting
MASTER VOL to any desired volume level. Setting MASTER VOL very high will send the power
section into overdrive, too.
PRESENCE
This control works in the amp’s power section to adjust the amp’s overall brilliance.
PRESENCE will have a less-noticeable effect when MASTER VOL is at lower settings. You may hear
some scratchiness when rotating PRESENCE. This is normal.
POWER & STANDBY
When powering up, switch POWER to ON while leaving STANDBY in the OFF
position to allow the tubes to warm up. After a half-minute or so, flip STANDBY up to the ON
position. To turn the amp off, simply flip both switches down to OFF. There’s no need to put the
amp in standby mode when shutting down.
Power Indicator
Illuminates when POWER is set to ON.
REAR PANEL CONTROLS AND FEATURES, Left to Right
FOOT SWITCH
Standard 1/4” jack for the included foot switch (depending on installed options).
Effects Loop (Optional)
SEND LEVEL, SEND jack, RETURN jack, RETURN LEVEL and TRUE BYPASS
switch are the interface to the powerful fully tube-buffered effects loop. For best performance with
guitar pedals, set SEND LEVEL to 5-7 and set RETURN LEVEL to 8-10, being sure to avoid audible
distortion in the return circuit. The Send signal is always present, regardless of the position of the
TRUE BYPASS switch.
IMPEDANCE
Matches the amplifier’s output impedance to your speaker cabinet(s).
SPEAKER
Two standard 1/4” speaker output jacks. Always use speaker cables - NOT guitar cables -
to connect speaker cabinets, or damage to the amplifier may occur. Do not operate the amplifier
without a speaker or suitable load connected, as this can cause damage to the amplifier.
Fuses
Replace with same type and rating only. The MAINS fuse is on the main power input to the
amplifier. The HT or High Tension fuse is on the B+ plate voltage supply.
Mains Input
Standard IEC power inlet. Always use a proper grounded power cable. Your amplifier
shipped with a Hospital Grade cable for reliability.
