4. SCHEMATIC DIAGRAMS AND P. C. BOARDS PATTERN
1. RESISTORS:
Indicated in n, 1/4W, 1/6W and 1/8W, ±5% tolerance
unless otherwise noted k; k Q, M;MQ (C) . + i %
(G) ; ± 2 %. (K) ; ± 10 %, (M) ; ± 20 % tolerance. '
2. CAPACITORS :
Indicated in capacity ( m F) / voltage (V) unless otherwise
noted p ; pF. Indication without voltage is 50V except
electrolytic capacitor.
a VOLTAGE, CURRENT :
'l-1 • 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 designation
* marked capacitors and resistors have parts numbers.
This is the basic schematic diagram, but the actual circuit
may vary due to improvements in design.
