Note:
• All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and
1 / W or less unless otherwise

specified.
• ¢ : internal component.
• U : B+ Line.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark : FM (RADIO SECTION)
r Refer to page 23 for IC Block Diagrams.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
