DIAGRAMS
For Schematic Diagrams.
Note:
• All capacitors are in µF unless otherwise noted. (p: pF)
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.
• f : internal component.
• C : panel designation.
• A : B+ Line.
• H : adjustment for repair.
•Total current is measured with no cassette installed.
•Power voltage is dc 12 V and fed with regulated dc power
supply from battery terminal.
•Voltages and waveforms are dc with respect to ground un-
der no-signal (detuned) conditions.
•Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
•Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.
• Signal path.
F : FM
f : AM
E : PB
a : REC
J : CD
d : LINE IN
For Printed Wiring Boards.
Note:
• X : parts extracted from the component side.
• f : internal component.
• : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
• Indication of transistor.
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
Note: The components identified by mark 0 or dotted
line with mark 0 are critical for safety.
Replace only with part number specified.
Caution:
Pattern face side: Parts on the pattern face side seen from
(Side B) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Side A) the parts face are indicated.
