3. SCHEMATIC AND PCB 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: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% un-
lass otherwise noted.
. CAPACITORS:
Unit: p:pF or uF unless otherwise noted.
Ratings: capacitor (uF)/voltage(V) unless othrewise noted.
Rated voltage: 50V except for electrolytic capacitors.
. COILS:
Unit: m:mH or pH unless otherwise noted.
. VOLTAGE AND CURRENT:
Tj ore V:
DC voltage (V) in PLAY mode unless otherwise noted.
<3 mA or © mA:
DC current in PLAY mode unless otherwise noted.
Value in( ) is DC current in STOP mode.
. OTHERS:
*@ or@ : Adjusting point.
. ~@ : 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-C] ON THE SCHEMATIC DIAGRAM:
* SCH-O indicates the drawing number of the schematic dia
gram. (SCH stands for schematic diagram.)
. SWITCHES (Underline indicates switch position):
