If the PHONO 1 Phono Stage is not functioning properly, please
check each of the following:
1.
Check that the AC Detachable Power Cord is plugged into
the Phono Stage’s Detachable Power Cord Socket (D) and is
connected to a
live
source of AC power. For instance, if using a
power bar, check that the bar is turned on.
2.
Be sure that the Power Switch (C) is in the “ON” position.
3.
Check that input & output connections are correct.
4.
Ensure that the phono stage is not in MUTE mode, or still in
the 40 second warm-up/turn-on cycle.
5.
Check that the AC Line Fuse inside the PHONO 1 chassis is
good. Be sure to
first
unplug the AC Detachable Power Cord
from the chassis rear before removing chassis covers to check the
fuse. For the fuse location see figure 6. To remove the fuse, sim-
ply push down and turn counter-clockwise the fuse holder and
remove the fuse. 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 type and rating (See specifi-
cations for fuse ratings).
7 .
Check to be sure that all the tubes are correctly and firmly seat-
ed in their tube sockets and that all nine contact pins are inserted
in each socket (i.e. no pins are bent over). Verify that an orange
glow (tube filament) is visible from inside of each tube when the
unit is on.
8.
If you are still experiencing any difficulty with your PHONO 1
Phono Stage, contact your dealer or distributor for assistance.
REPLACEMENT OF THE TUBES
Sonic Frontiers strongly discourages non-factory replacement of
the tubes. The tubes supplied are measured, selected, and
matched in pairs - channel to channel and triode
section to triode section - for optimum performance.
Problems arising from non-SFI supplied tubes will not be covered
under warranty.
If replacement tubes are needed, desired or required contact
Sonic Frontiers for assistance.
