23. 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.
24. STANDBY 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.
25. POWER 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.
REAR PANEL OVERVIEW:
1. VOLTAGE 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.
WARNING: ONLY A FACTORY QUALIFIED SERVICE TECHNICIAN SHOULD EVER ATTEMPT THIS ALTERA-
TION.
2. VOLTAGE SELECTOR 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.
3. 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.
WARNINGS:
• NEVER OPEN THIS FUSE HOLDER WITH THE POWER CORD PLUGGED IN .
• USE ONLY THE FUSE VALUE AS INDICATED IN THE VOLTAGE CHART.
• NEVER ATTEMPT TO DISABLE THE MAINS POWER FUSE.
4. FOOTSWITCH 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.
