• : internal component.
¢
• 1 : fusible resistor.
Note: The components identified by mark ! or dotted
line with mark ! are critical for safety.
Replace only with part number specified.
• U : B+ Line.
• H : adjustment for repair.
• Power voltage is dc 9V and fed with regulated dc power
supply from battery terminal.
• Voltages are dc with respect to ground under no-signal
(detuned) conditions.
no mark : FM (Radio section), CD STOP (CD section)

• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
