1. When ordering service parts, be sure to refer to
"PARTS
LIST of EXPLODED
VIEWS"
or "PCB
PARTS LIST".
2. Since these are basic circuits, some parts of them or the
vaiues of some components may be changed for improve-
ment.
3. RESISTORS:
Unit: &:kQ, 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):+ 10%, (M):+20% or +5%
unless otherwise noted.
4. CAPACITORS:
Unit: p:pF or 1 F unless otherwise noted.
Ratings ; capacitor (uF) /voltage (V) unless otherwise noted,
Rated voltage : 50V except for electrolytic capacitors.
'5. COILS:
Unit: m:mH or |.H unless otherwise noted.
6. VOLTAGE AND CURRENT:
YJ : DC voltage (V) in PLAY mode unless otherwise noted.
©mAor+mA:
DC current In PLAY mode unless otherwise noted,
Value in({
) {is DC current in STOP mode.
7. OTHERS:
@ »
: Signal route.
©@ : Adjusting point.
@ ¥ (Red) : Measurement point.
@The A mark found on some
component parts Indicates the im-
portance of the safety factor of the parts. Therefore, when replacing,
be sure to use parts of identical designation.

1. This P.C.8. connection diagram Is viewed from the parts mounted side.
2. The parts which have been mounted on the board can be replaced with
those shown with the corresponding wiring symbols listed In the above Table.
3. The capacttor terminal marked with [__]shows negative terminal.
4. The diode marked with © shows cathode side.
5, The transistor terminal marked wth [—_}shows emitter.
