3. SCHEMATIC DIAGRAM
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.
3 marked capacitors and resistors have parts numbers.
This is the basic schematic diagram, but the actual circuit
may vary due to improvements in design.
