1. Be careful not to allow metallic dust, etc. to enter
inside the unit, be cause its motor is comprised of
magnetic elements.

2. X809
through
X812
should
be of the
same rank.
(There are four different rankings avail-
able on the market as follows:
2SD571
K1,K2,L1
and L2
Be sure
to use only one
rank of those
transistors being replaced.)
3. When replacing either of these transistors
2SC1775A(F7),
X813
or
X818,
they
should be replaced together as a pair both
being of the same rank.
4. —— indicates positive
B power supply.
5. =—— indicates signal path.
6. When
replacing
the parts
in the dark-
ened
area
and
those
marked
with
A , be sure
to use the designated parts
to ensure safety.
7. This is the standard circuit diagram.
The
design and contents
are subject to
