3. Please checking the grating after changing the ser-
vice pickup unit(see page 43).

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
ATUNER AMP UNIT
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.
