6-10. SCHEMATIC DIAGRAM — MAIN SECTION (2/3) — • Refer to page 38 for IC Block Diagrams.
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

W or less unless otherwise
specified.
•
U
: B+ Line.
• Power voltage is dc 9 V and fed with regulated dc power
supply from battery terminal.
• Voltage and waveforms are dc with respect to ground
under no-signal conditions.
no mark : CD (STOP)
• Voltages are taken with a VOM (Input impedance 10 M
Ω
).
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.
