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-
less 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:
: Signal voltage at rated output.
SJ]
or & V:
DC voltage (V) at no input signal unless otherwise noted.
Value in(
) is DC voltage at rated power.
o mA or — mA:
DC current at no input signa! unless otherwise noted.
OTHERS:
*@ or@ : Adjusting point.
o
: 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:
* SCH-C indicates the drawing number of the schematic dia
gram. (SCH stands for schematic diagram.)
. SWITCHES (Underline indicates switch position):
