NOTE FOR SCHEMATIC DIAGRAMS
(Type 4A)
1. When ordering service parts, be sure to refer to
"PARTS
LIST of EXPLODED
VIEWS"
or "PCB
PARTS LIST".
. Since these are basic circuits, some
parts of them or the
values of some components
may be changed for improve-
ment.
. RESISTORS:
Unit: k:k2, M:MQ, or Q unless otherwise noted.
Rated
power:
1/4W,
1/6W,
1/8W,
1/10W
unless
otherwise
noted.
Tolerance: (F): +1%, (G): +2%, (K): 410%, (M): +20% or +5% un-
less otherwise noted.
. CAPACITORS:
Unit: p:pF or wF unless otherwise noted.
Ratings: capacitor (uF)/ voltage (V) unless otherwise noted.
Rated voltage: 50V except for electrolytic capacitors.
. COILS:
Unit: m:mH or pwH unless otherwise noted.
. VOLTAGE AND CURRENT:
S__lor+Vv:
DC voltage (V) in PLAY mode unless otherwise noted.
© mA
or+
mA:
DC current in PLAY mode unless otherwise noted.
Value in(
) is DC current in STOP mode.
OTHERS:
¢@or@
: Adjusting point.
6
<@
=: Measurement point.
© The A, mark found on some component parts indicates the im-
portance of the safety factor of the parts. Therefore, when re-
placing, be sure to use parts of identical designation.
. SCH—O ON THE SCHEMATIC DIAGRAM:
e SCH—O indicates the drawing number of the schematic dia-
gram. (SCH stands for schematic diagram.)
