If at any time the Amp 1 fails to work properly, consult this
checklist:
1. Check that the AC Detachable Power Cord is plugged into
the Amp 1 Detachable Power Cord Socket (C) and is con-
nected to a live source of AC power. For instance, if using a
power bar, check that the bar is turned on.
2. Ensure that all Input and Output connections are secure for
a proper electrical contact.
3. DISCONNECT THE AC POWER CORD, wait 5 minutes and
check that:
• A slo-blo fuse, with a rating of 3.5 Amp/250 V (1.6 Amp/250
V for European and Asian versions), is installed in the fuse
holder.
• The AC power fuse is intact and has not blown. If the fuse
has blown, the thin metal conductor will have melted and the
glass may appear “smoked”. If the fuse has blown, replace
with a fuse of the same rating (3.5 Amp/250V slo-blo for 100
to 120 volt countries and 1.6 Amp/250V slo-blo for 220 to 240
volt countries). (See Figure 5)
NOTE: Under no circumstances should you replace the AC
power fuse with one of a higher current rating! Doing so may
cause further damage to the Amp 1 and will also void the
warranty. In addition, your continued protection from risk of
fire or shock would be seriously compromised.
• Ensure the tubes are plugged firmly into their sockets as
described in “INSERTION OF THE TUBES”.
4. Be sure the rest of the system is functioning properly (i.e.
source unit, power amplifiers, cables and connections, etc.).
5. With tubes, fuses, covers and power cords in place, check
that the LED (A) is lighted (glowing light green). If all of the
above troubleshooting steps have been followed and the LED
is not lighted (remains dark green), contact your dealer or
distributor for assistance.
