• Refer to page 25 for Printed Wiring Board.
(Page 23)
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 ¹/4 W or less unless otherwise
specified.
• ¢ : internal component.
• C : panel designation.
• U : B+ Line.
• Power voltage is dc 14.4V and fed with regulated dc power
supply from ACC and BATT cords.
• Voltage and waveforms are dc with respect to ground
under no-signal conditions.
no mark : FM
< > : TAPE PLAYBACK
∗ : Impossible to measure
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production tol-
erances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production tol-
erances.
• Circled numbers refer to waveforms.
• Signal path.
