Setup
The INT-25 measures 17"w x 17.9"d x 6"h and weighs 51 pounds. You may place it
wherever you please, but it is going to need lots of free air for adequate cooling.
There needs to be space above and unobstructed space around the sides to allow
for proper air fl ow. This is a factor in reliable operation and long life.
The INT-25 is expected to have a 25-degree C rise at the sinks when running. Under
normal operation you should be able to grasp the heat-sinks for 5 to 10 seconds
without heat being an issue. If the amplifi er becomes too hot to touch please
contact your dealer or the factory for assistance.
AC power is provided by a conventional detachable IEC 320 grounded AC mains
power cord. This power cord serves as the safety disconnect. The power cord should
be removed from the wall in the event of electrical storms or when the INT-25 is not
going to be used for long periods.
The amplifi er is designed to perform well with the included power cord. Should you
select an "after market" detachable power cord, please confi ne your selection to
those rated by local authorities to carry a minimum of 13A at 250V.
At idle the INT-25 will consume 275W from the AC mains. The required voltage and
correct fuse value will be indicated on the rear of the amplifi er. Both 100 Vac and 120
Vac builds are fused at 5A. The 220 - 240 Vac build amplifi ers are fused at 2.5 amp.
In all instances the fuses are type 5x20mm slow blow (time delay) fuse rated for 250
VAC service. Do not substitute fuses of different values or physical size. If you cannot
source equivalent replacement fuses locally, please contact your dealer or the
factory.
This product ships from the factory with a replacement fuse included in addition to the
fuse installed in the chassis fuse holder. The fuse holder is located on the rear panel
of the amplifi er. Changing the fuse requires a close fi tting straight blade screwdriver,
and the power cord should be unplugged from the wall. If you are not comfortable
