Note:
• All capacitors are in µF unless otherwise noted. (p: pF)
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and

specified.
• % : indicates tolerance.
f
• : internal component.
• 2 : nonflammable resistor.
• 5 : fusible resistor.
Note: The components identified by mark 0 or dotted line
with mark ! are critical for safety.
Replace only with part number specified.
• C : panel designation.
• A : B+ Line.
• B : B– Line.
• H : adjustment for repair.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark: TUNER (FM/AM)
( ) : CD PLAY

[ ]: TAPE REC
* : Impossible to measure
• 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.
• Signal path.
