2.CAPACITORS :
Indicated in capacity (uF)/voltage(V) unless otherwise noted p; pF. Indication
without voltage is 50V except electrolytic capacitor.
3.VOLTAGE, CURRENT :
Ld
; 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 inportance of the
safety factor of the part. Therefore, when replacing, be sure to use parts of
identical designation.
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.
