Safety Tips
Fuses:
There are many safety features built into a Zesto power amp. The purpose of a fuse is
to protect the amplifier, sometimes they wear out and sometimes the fuse will blow.
The mains fuse is the most likely fuse to blow, not the speaker fuse.
The mains fuse is located in a drawer like compartment in the IEC power connector.
120 Volts AC mains is 10 Amp 5mm x 20mm slow blow fuse.
220V, 230V/240V 50/60Hz mains is 6.3 Amp
5mm x 20mm slow blow fuse.
All fuse types are not created equal. For example, a Slow Blow fuse is not the same as
a Standard fuse.
Warning!
The Eros 500 is designed for “Slow Blow” fuses. If you install a standard
fuse, the fuse will blow when you turn the amp on.
If a slow blow fuse blows, the most likely cause is an output tube. If you replace the tube
and the fuse blows again, contact your dealer.
Important!
Any use of aftermarket performance fuses used in the IEC mains will
VOID the manufacturer’s warranty
.
Speaker fuses
The fuses directly under the binding post are designed to blow to protect the amplifier in
case there is a short in the speaker or speaker cable.
Speaker fuses are not the mains fuse.
Speaker fuses are 6mm x 32mm 7A & 10A slow blow fuses.
Safety Tips!
Power amp output tubes (KT150) get very hot when operating properly; tubes can
exceed 300 degrees Fahrenheit.
Avoid
moving your amplifier with hot tubes. Tubes are the most vulnerable when they
are hot, and it will break the filament not the glass. However, you can change a hot tube
as long as the amp is turned off and both LED lights are off.
To protect your speakers, turn the power amp OFF when changing any cables in your
system.
If you change cables or move the amp, always double check that your power cable is
properly inserted. A loose power connection can blow a fuse and possibly damage this
amplifier.
If you break a tube, turn unit off immediately. Wait until both LEDs are off for the high
voltage to discharge completely to replace it.
If you spill any liquids on the unit, turn off immediately and call the factory.
