1. RESISTORS:
Indicated in Q , 1/4W, 1/6W, 1/8W and 1/10W,
+ 5%
tolerance unless otherwise noted k;kQ,
M;MQ,
(F);+
1%, (G); & 2%, (K); + 10%, (M); + 20% tolerance.
2. CAPACITORS:
Indicated in capacity ( uF) /voltage (V) unless otherwise
noted
p;pF.
Indication without voltage is 50V except
electrolytic capacitor.
:
3. VOLTAGE, CURRENT:
\___] ;DC voltage (V) at play state.
mA
;DC current at play state.
;Value in ( ) is DC current at stop state.
4, OTHERS:
=» ; Signal route.
@; Adjusting point.
The A\ mark found on some component parts indicates the
importance
of the safety factor of the part. Therefore,
when replacing, be sure to use parts of identical desig-
nation.
;
X marked capacitors and resistors have parts numbers.
This is the basic schematic diagram, but the actual circuit
may vary due to improvements in design.
