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.
•%: indicates tolerance.
• f : internal component.
• 2 : nonflammable resistor.
• 5 : fusible resistor.
• C : panel designation.
• A : B+ Line.
• B : B– Line.
• H : adjustment for repair.
•Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark: TUNER (FM/AM)
( ): CD PLAY
< >: TAPE PLAY
[ ]: TAPE REC
* : Impossible to measure
•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.
• Signal path.
F : TUNER (FM/AM)
E : TAPE PLAY (DECK A)
d : TAPE PLAY (DECK B)
G : RECORD
J : CD PLAY (ANALOG OUT)
c : CD PLAY (DIGITAL OUT)
j : GAME IN (AUDIO)
k : GAME IN (VIDEO)
N : MIC INPUT
• Abbreviation
AUS : Australian model
E2 : 120V AC Area in E model
