6-14. PRINTED WIRING BOARD — SOUND SECTION — • Refer to page 17 for Circuit Boards Location.
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.
• C : panel designation.
• U : B+ Line.
• Power voltage is dc 9 V and fed with regulated dc power
supply from battery terminal.
• Voltage is dc with respect to ground under no-signal
(detuned) condition.
no mark : FM
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
F : FM
Note on Printed Wiring Boards:
• X : parts extracted from the component side.
• b : Pattern from the side which enables seeing.
