Note on Schematic Diagram:
• 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
specified.
• C : panel designation.
CN801
2P
• A : B+ Line.
• Power voltage is dc 9 V and fed with regulated dc power
S901 supply from battery terminal.
PUSH OPEN/CLOSE
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : TUNER (FM/AM)
[ ] : CD PLAY
〈〈 〉〉 : TAPE PLAY
• 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.
• Abbreviation
AR : Argentina model
KR : Korean model
SP : Singapore model
TW : Taiwan model
