CHAPTER 6. CIRCUIT SCHEMATICS AND PARTS LAYOUT
[1] Notes On Schematic Diagram
[2]  Types Of Transistor And LED
Resistor:
To differentiate the units of resistors, such symbol as 
K and M are used: the symbol K means 1000 ohm 
and the symbol M means 1000 kohm and the 
resistor without  any  symbol is ohm-type resistor. 
Besides, the one with “Fusible” is a fuse type.
Capacitor:
To indicate the unit of capacitor, a symbol P is used:
this symbol P means pico-farad and the unit of the 
capacitor without such a symbol is microfarad. As to 
electrolytic capacitor, the expression “capacitance/ 
withstand voltage” is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type
Schematic diagram  and Wiring Side of P.W.Board 
for this model are  subject to change for
improvement without prior notice.
The indicated voltage in each  section is the one 
measured  by Digital Multimeter  between  such  a 
section and the chassis with no signal given.
Parts  marked with “
” are important for 
maintaining the safety of the set. Be sure to replace 
these parts with specified ones for maintaining the 
safety and performance of the set.
