TUNER AMP UNIT

For resistors and capacitors in the circuit diagrams, their resistance values or
capacitance values are expressed in codes:

Ex. *Resistors
Code Practical value
123 12k ohms
103 10k ohms

*Capacitors
Code Practical value
103 0.01uF
101/10 100uF/10V

The

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.

Symbol indicates a resistor.
No differentiation is made between chip resistors and
discrete resistors.

NOTE :

Symbol indicates a capacitor.
No differentiation is made between chip capacitors and
discrete capacitors.
