Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolytics
C826

and tantalums.
• All resistors are in Ω and
specified.
• A : B+ Line.
• Power voltage is dc 9 V and fed with regulated dc power
CN801
supply from battery terminal.
2P
• Voltages and waveforms are dc with respect to ground
S701
(CD LID OPEN/CLOSE)
under no-signal (detuned) conditions.
no mark : TUNER (FM/AM)
[
〈〈
• 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-
m
tion tolerances.
• Circled numbers refer to waveforms.
