REAR PANEL
Mains Input
Your Hundred Duo Twelve has a detachable power cord that connects to the chassis AC connector labeled Mains
Input. Always use this cord and, in the event that the power cord requires replacement, replace it with the same type
of power cord. Consult your RIVERA dealer for further information. Be sure to use a grounded electrical mains
power supply socket whenever possible. These outlets have a grounding pin in addition to the normal line and neu-
tral pin. The power cord supplied with your Hundred Duo Twelve has a 3-pin plug. Do not cut off or damage the
ground pin. If the available electrical outlet is of the older 2-pin type, use a suitable ground-lift adapter.
The U.S.A., Canada, and Japan share a common CSA/UL-style cord. Most of Europe and Scandinavia utilize
a Euro plug and have a SEMKO/VDE-style cord. Australia uses a different type of plug, as does England.
Note: Avoid using long extension cords. Long cords have sufficient resistance to electrical current that the
voltage arriving at your amp can be significantly reduced. This can have a bad effect on your tone.
Mains Fuse
This AC line fuse protects your amplifier from damage due to shorts, momentary surges, and defective power
tubes. In the event of a fuse failure, always replace it with the same type of fuse.
Note: Always turn the amp off and wait about five minutes before replacing a fuse. This allows
the parts to cool and high voltages to dissipate.
For 100VAC versions, the Mains Fuse is: 5 Amp, 250 Volt Slo-Blo type (size 3AG, or MDL)
For 115VAC versions, the Mains Fuse is: 4 Amp, 250 Volt Slo-Blo type (size 3AG, or MDL)
For 230VAC versions, the Mains Fuse is: T 2A (time-delay, 5mm x 20mm size)
HT Fuse
The power amplifier circuit has its own fuse for protecting the output section from short circuits and tran-
sient current peaks that exceed the normal current draw. These conditions are usually caused by a bad tube.
When a short circuit or transient peak causes the fuse to blow, the output tubes should be checked and
replaced, if necessary.
For 100VAC and 115VAC versions, the HT Fuse is: 1 Amp, 250 Volt Slo-Blo type (3AG, or MDL)
For 230VAC versions, the HT Fuse is: T 1A (time-delay, 5mm x 20mm size)
Repeated blowing of this fuse is a clear indicator of a defective output tube.
Always use the correct fuse value when replacing the HT Fuse.
If the Mains Fuse or the HT Fuse repeatedly blows, refer your amp to your local RIVERA dealer or contact us
at (818) 890-2826 for further service assistance.
DO NOT REMOVE CHASSIS.
REPLACE FUSE WITH SAME TYPE AND RATING.
