MAINTENANCE
Quick-Acting Fuses
These fuses for right and left channels are also de-
signed to protect the transistors by blowing instantly
if shorting occurs between connections at a speaker
system terminal.
If , after the POWER switch is
turned on and the dial scales li ght up, neit her
channel operates or only one operates normall y, is
either because one or both Quick-Acting fuses have
blown.
In this case, remove the 3 50A 's power
supply cord from its outlet, remove the wood case
from the chassis, and check to see if the fuses are
blown. Replace them with identical 2.
5A fuses a ft er
finding and eliminating the source of trouble that
caused them to blow.
AC Outlet
The 350A is provided with an AC outl et on the back
pane
l. It is controlled by the POWER switch on
the front panel.
CAUTION: T he maximum capacity of this outlet
is 50V A. ever use it beyond its rated capacity.
The voltage supplied by the
AC outlet
is the same as the
po
wer supply voltage used.
Power Fuse
Should the ampli fi er fa il to operate and the di al
scales
fa il to light up when the POWER switch is
turned on , the probable cause is either a power
stoppage or a blown fuse.
To check, remove the
350A s power supply cord from its outlet, turn the
fuse holder on the
rear panel counterclockwise, and
remove the
fu s e. If it is blown, replace it with a
new glass-tubed fuse of the same capacity (
100-----
1 27 V -2 A, 22 0----- 250V- 1.5A) after de termining
and eliminating the trouble source that caused the
fu se to blow. Using wire or a fuse of a different
capacity as a stop-gap measure is dangerous and
should be avoide
d.
DIN Socket
If your tape deck has a Dl socket, it may be
connected to the 350A simply by the use of a cable
with a 5-pin DIN connector on each end. Insert
each connector to the DI socket
on the receiver's
r
ear panel and into the on e on the tape deck. The
DI connection system, designed to simplify inter-
connections between the tape deck and amplifier,
is based on the German DIN Standard s.
