Genz-Benz EL DIABLO 60 ユーザーズマニュアル

GLOBAL VOLUME CONTROL – This knob controls the fi nal output stage of the amplifi er and is the master 

volume for EL DIABLO.  It should be noted that this control is best set between the 9 o’clock and 2 o’clock positions.  
Each channel volume should be adjusted accordingly to achieve the desired total amplifi er output.  For lower volume 
settings, you can power the unit down to 30 watts with the PENTODE / TRIODE power level selector switch on the 
back panel.

SWITCH – The standby switch removes the high voltage from the plate circuit of the output tubes 

to protect the tubes from “cathode stripping” when fi rst powering up the amplifi er.  The recommended start-up  
procedure is to place the standby switch in the standby position, turn on the power switch and allow the amplifi er to 
warm up for at least 30 seconds before switching the standby switch to the operate position.  This will help to prolong 
the life of your output tubes.

SWITCH – This switch turns on the AC power to the amp.  When this switch is turned on, power is 

applied to the heater circuits of all tubes, the high voltage power supplies are allowed to stabilize and the low voltage 
power supplies are energized.  Power should be switched on only with the standby switch in the standby  
position.  Refer to #25 for information concerning the operation of the standby function.

CHART – Your EL DIABLO 60 is truly a “world class” amplifi er.  This voltage chart is provided 

so that choosing the correct fusing for the desired international country is simple and accurate.  The EL DIABLO’s 
internal power transformer can be re-wired for 100 volt use for JAPAN.  

SWITCH - This switch changes the voltage of the AC power with which the amp will 

operate.  115 volts is the standard in the USA and CANADA.  230 volts is the standard for most of EUROPE and 
SOUTH AMERICA.  Consult the voltage chart if you plan to use this amp for a different voltage other than how it was 
shipped from the factory so that the proper fuse can be inserted.  The DIABLO 60 is rated for operation on both 50 
Hz and 60 Hz power sources.

IEC RECEPTACLE & FUSE HOLDER – The detachable power cord should be inserted here before the 

cord is plugged into an AC power source.  Within the bottom portion of this receptacle is a small drawer that holds 
the mains power fuse.  An extra fuse is included in this plastic receptacle.  It may be necessary to use a small tool to 
pry the small drawer open.

INPUT – This 5 pin DIN connector is where EL DIABLO’s 4-button footswitch should be 

attached. A 25-foot cord is attached to the heavy-duty steel footswitch.  This should provide plenty of room for the 
performer to get out in front of the amp.  Some internal circuitry “clicking” may be heard if the amp is on when this 
footswitch is plugged in.  This is normal and is actually part of the circuitry that provides the noiseless switching on 
the EL DIABLO 60. NOTE: The front panel function switches over-ride the footswitch functions. The front panel func-
tion switches should be in the out position when the footswitch is used.
